150mA SOT-23 Ultra Low Noise CMOS RF-LDO™ Regulator Impala Linear Corporation 6(408) 574-3939 www.impalalinear.com April 1999 ILC7082 1.3 Shutdown (ON/OFF) Operation The ILC7082 output can be turned off by applying 0.4V or less to the device’s ON/OFF pin (pin 3). In shutdown mode, the ILC7082 draws less than 1mA quiescent current. The output of the ILC7081 is enabled by applying 1.5V to 13V at the ON/OFF pin. In applications were the ILC7082 output will always remain enabled, the ON/OFF pin may be con- nected to V IN (pin 1). The ILC7082’s shutdown circuitry includes hysteresis, as such the device will operate proper- ly even if a slow moving signal is applied to the ON/OFF pin. The device’s shutdown pin includes a 2MW internal pull down resistor connected to ground. Short Circuit Protection The ILC7082 output can withstand momentary short circuit to ground. Moreover, the regulator can deliver very high out- put peak current due to its 1A instantaneous short circuit current capability. Thermal Protection The ILC7082 also includes a thermal protection circuit which shuts down the regulator when die temperature exceeds 170°C due to overheating. In thermal shutdown, once the die temperature cools to below 160°C, the regula- tor is enabled. If the die temperature is excessive due to high package power dissipation, the regulator’s thermal cir- cuit will continue to pulse the regulator on and off. This is called thermal cycling. Excessively high die temperature may occur due to high dif- ferential voltage across the regulator or high load current or high ambient temperature or a combination of all three. Thermal protection protects the regulator from such fault conditions and is a necessary requirement in today’s designs. In normal operation, the die temperature should be limited to under 150°C. Adjustable Output Voltage Figure 5 shows how an adjustable output voltage can be easily achieved using ILC7082-Adj. The output voltage, V OUT is given by the following equation: VOUT = 1.24V x (R1/R2 + 1) For best results, a resistor value of 470kW or less may be used for R2. The output voltage can be programmed from 2.5V to 12V. Note that an external capacitor should not be connect- ed to the adjustable feedback pin (pin 4). Connecting an external capacitor to pin 4 may cause regulator instability and lead to oscillations. Maximum Output Current The maximum output current available from the ILC7082 is limited by the maximum package power dissipation as well as the device’s internal current limit. For a given ambient temperature, T A, the maximum package power dissipation is given by: PD(MAX) = (TJ(MAX) - TA) / θJA where TJ(MAX) = 150°C is the maximum junction temperature and θJA = 333°C/W is the package thermal resistance. For example at T A = 85°C ambient temperature, the maximum package power dissipation is; PD(MAX) = 195mW. The maximum output current can be calculated from the fol- lowing equation: IOUT(MAX) < PD(MAX) / (VIN - VOUT) For example at VIN = 6V, VOUT = 5V and TA = 85°C, the max- imum output current is I OUT(MAX) < 195mA. At higher output current, the die temperature will rise and cause the thermal protection circuit to be enabled. APPLICATION HINTS Figure 4 shows the typical application circuit for the ILC7082.

150mA SOT-23 Ultra Low Noise CMOS RF-LDO™ Regulator Impala Linear Corporation 7(408) 574-3939 www.impalalinear.com April 1999 ILC7082 1.3 Input Capacitor An input capacitor CIN of value 1µF or larger should be con- nected from V IN to the main ground plane. This will help to filter supply noise from entering the LDO. The input capaci- tor should be connected as close to the LDO regulator input pin as is practical. Using a high-value input capacitor will offer superior line transient response as well as better pow- er supply ripple rejection. A ceramic or tantalum capacitor may be used at the input of the LDO regulator. Note that there is a parasitic diode from the LDO regulator output to the input. If the input voltage swings below the reg- ulator’s output voltage by a couple of hundred milivolts then the regulator may be damaged. This condition must be avoided. In many applications a large value input capacitor, C IN, will hold VIN higher than VOUT and decay slower than VOUT when the LDO is powered off. Output Capacitor Selection Impala strongly recommends the use of low ESR (equiva- lent series resistance) ceramic capacitors for C OUT and CNOISE The ILC7082 is stable with low ESR capacitor (as low as zero Ω ). The value of the output capacitor should be 1µF or higher. Either ceramic chip or a tantalum capacitor may be used at the output. Use of ceramic chip capacitors offer significant advantages over tantalum capacitors. A ceramic capacitor is typically cheaper than a tantalum capacitor, it usually has a smaller footprint, lower height, and lighter weight than a tantalum capacitor. Furthermore, unlike tantalum capacitors which are polarized and can be damaged if connected incorrectly, ceramic capacitors are non-polarized. Low value ceramic chip capacitors with X5R or X7R dielectric are available in the 100pF to 4.7mF range. Beware of using ceramic capaci- tors with Y5V dielectric since their ESR increases significant- ly at cold temperatures. Figure 12 shows a list of recom- mended ceramic capacitors for use at the output of ILC7082. Note: If a tantalum output capacitor is used then for stable operation Impala recommends a low ESR tantalum capaci- tor with maximum rated ESR at or below 0.4W. Low ESR tantalum capacitors, such as the TPS series from AVX Corporation (www.avxcorp.com) or the T495 series from Kemet (www.kemet.com) may be used. In applications where a high output surge current can be expect- ed, use a high value but low ESR output capacitor for superior load transient response. The ILC7082 is stable with no load. Noise Bypass Capacitor In low noise applications, the self noise of the ILC7082 can be decreased further by connecting a capacitor from the noise bypass pin (pin 4) to ground (pin 2). The noise bypass pin is a high impedance node as such care should be taken in printed circuit board layout to avoid noise pick-up from external sources. Moreover, the noise bypass capacitor should have low leakage. Noise bypass capacitors with a value as low as 470pF may be used. However, for optimum performance, use a 0.01mF or larger, ceramic chip capacitor. Note that the turn on and turn off response of the ILC7082 is inversely proportional to the value of the noise bypass capacitor. For fast turn on and turn off, use a small value noise bypass capacitor. In appli- cations were exceptionally low output noise is not required, consider omitting the noise bypass capacitor altogether. The Effects of ESR (Equivalent Series Resistance) The ESR of a capacitor is a measure of the resistance due to the leads and the internal connections of the component. Typically measured in m Ω (milli-ohms) it can increase to ohms in some cases. Wherever there is a combination of resistance and current, voltages will be present. The control functions of LDOs use two voltages in order to maintain the output precisely; V OUT and VREF. With reference to the block diagram in figure 4, V OUT is fed back to the error amplifier and is used as the supply voltage for the internal components of the ILC7082. So any change in V OUT will cause the error amplifier to try to compensate to maintain V OUT at the set level and noise on V OUT will be reflected into the supply of each internal components of the ILC7082. So any change in V OUT will cause the error ampli- fier to try to compensate to maintain VOUT at the set level and noise on VOUT will be reflected into the supply of each inter- nal circuit. The reference voltage, V REF, is influenced by the CNOISE pin. Noise into this pin will add to the reference volt- age and be fed through the circuit. These factors will not cause a problem if some simple steps are taken. Figure 5 shows where these added ESR resistances are present in the typical LDO circuit. With this in mind low ESR components will offer better per- formance where the LDO may be subjected to large load transients current. ESR is less of a problem with C IN as the voltage fluctuations at the input will be filtered by the LDO. ILC7082 VIN SOT-23-5 CIN ON OFF 12 3 Figure 5: ESR present in C OUT and CNOISE
150mA SOT-23 Ultra Low Noise CMOS RF-LDO™ Regulator Impala Linear Corporation 8(408) 574-3939 www.impalalinear.com April 1999 ILC7082 1.3 However, being aware of these current flows, there is also another potential source of induced voltage noise from the resistance inherent in the PCB trace. Figure 6 shows where the additive resistance of the PCB can manifest itself. Again these resistances may be very small, but a summation of several currents can develop detectable voltage ripple and will be amplified by the LDO. Particularly the accumulation of current flows in the ground plane can develop significant voltages unless care is taken. With a degree of care, the ILC7082 will yield outstanding performance. Printed Circuit Board Layout Guidelines As was mentioned in the previous section, to take full advantage of any high performance LDO regulator requires paying careful attention to grounding and printed circuit board (PCB) layout. Figure 7 shows the effects of poor grounding and PCB lay- out magnified by the ESR and PCB resistances and the accumulation of current flows. Note thatparticularly during high output load current, the LDO regulator’s ground pin and the ground return for C OUT and C NOISE are not at the same potential as the system ground. This is due to high frequency impedance caused by PCB’s trace inductance and DC resistance. The current loop between C OUT, C NOISE and the LDO regulator’s ground pin will degrade performance of the LDO. Figure 8 shows an optimum schematic. In this schematic, high output surge current has little effect on the ground cur- rent and noise bypass current return of the LDO regulator. Note that the key difference here is that C OUT and CNOISE are directly connected to the LDO regulator’s ground pin. The LDO is then separately connected to the main ground plane and returned to a single point system ground. The layout of the LDO and its external components are also based on some simple rules to minimize EMI and output voltage ripple.
