- Pagers General Description The TC1016 is a high-accuracy (typically ±0.5%), CMOS upgrade for bipolar low dropout regulators (LDOs). The TC1016 is offered in both the SC-70 and SOT-23 packages. The SC-70 package represents a 50% footprint reduction versus the popular SOT-23 package. Developed specifically for battery-powered systems, the device’s CMOS construction consumes only 53 µA typical supply current over the entire 80 mA operating load range. This can be as much as 60 times less than the quiescent operating current consumed by bipolar LDOs. With small-space requirements and cost in mind, the TC1016 was developed to be stable over the entire input voltage and output current operating range using low value (1 µF ceramic), low Equivalent Series Resistance (ESR) output capacitors. Additional integrated features (such as shutdown, overcurrent and overtemperature protection) further reduce board space and cost of the entire voltage-regulating application. Key performance parameters for the TC1016 are low drop out voltage (150 mV (typ.) at 80 mA output current), low supply current while shutdown (0.05 µA typical) and fast stable response to sudden input voltage and load changes.

Regulation is measured at a constant junction temperature using low duty cycle pulse testing. Load regulation is tested over a load range from 0.1 mA to the maximum specified output current. Changes in output voltage due to heating effects are covered by the Thermal Regulation specification. Dropout voltage is defined as the input-to-output differential at which the output voltage drops 2% below its nominal value at a 1V differential. Thermal regulation is defined as the change in output voltage at a time T after a change in power dissipation is applied, excluding load or line regulation effects. Specifications are for a current pulse equal to Ilmax at VIN = 6V for t = 10 msec. The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable juction temperature and the thermal resistance from junction-to-air (i.e. TA, TJ, θJA). Exceeding the maximum allowable power dissipation causes the device to initiate thermal shutdown. Please see Section 5.0 “Thermal Considerations” of this data sheet for more details.

TABLE 3-1: PIN FUNCTION TABLE 3.1 Shutdown Control Input (SHDN) The regulator is fully enabled when a logic-high is applied to SHDN. The regulator enters shutdown when a logic-low is applied to this input. During shutdown, the output voltage falls to zero and the supply current is reduced to 0.05 µA (typ.) 3.2 Ground Terminal (GND) For best performance, it is recommended that the ground pin be tied to a ground plane. 3.3 Regulated Voltage Output (VOUT) Bypass the regulated voltage output to GND with a minimum capacitance of 1 µF. A ceramic bypass capacitor is recommended for best performance. 3.4 Unregulated Supply Input (VIN) The minimum VIN has to meet two conditions in order to ensure that the output maintains regulation: VIN ≥2.7V and VIN ≥ [(VR + 2.5%) + VDROPOUT]. The maximum VIN should be less than or equal to 6V. Power dissipation may limit VIN to a lower potential in order to maintain a junction temperature below 125°C. Refer to Section 5.0 “Thermal Considerations”, for determining junction temperature. It is recommended that VIN be bypassed to GND with a ceramic capacitor. 5-Pin SC-70 Pin No. 5-Pin SOT-23 Name Function SHDN Shutdown control input NC No connect GND Ground terminal VOUT Regulated voltage output VIN Unregulated supply input

DS21666B-page 11 TC1016 5.0 THERMAL CONSIDERATIONS 5.1 Thermal Shutdown Integrated thermal-protection circuitry shuts the regulator off when die temperature exceeds approximately 160°C. The regulator remains off until the die temperature drops to approximately 150°C. 5.2 Power Dissipation The TC1016 is available in the SC-70 package. The thermal resistance for the SC-70 package is approxi- mately 450°C/W when the copper area used in the PCB layout is similar to the JEDEC J51-7 high thermal conductivity or Semi G42-88 standards. For applica- tions with larger or thicker copper areas, the thermal resistance can be lowered. See AN792 “A Method to Determine How Much Power a SOT23 Can Dissipate in an Application” (DS00792), for a method to determine the thermal resistance for a particular application. The TC1016 power dissipation capability is dependant upon several variables: input voltage, output voltage, load current, ambient temperature and maximum junction temperature. The absolute maximum steady- state junction temperature is rated at 125°C. The power dissipation within the device is equal to: EQUATION 5-1: The VIN x IGND term is typically very small when com- pared to the (VIN-VOUT) x ILOAD term simplifying the power dissipation within the LDO to be: EQUATION 5-2: To determine the maximum power dissipation capability, the following equation is used: EQUATION 5-3: Given the following example: Find: Internal power dissipation: Junction temperature: Maximum allowable dissipation: In this example, the TC1016 dissipates approximately 82.2 mW and the junction temperature is raised 37°C over the 55°C ambient to 92°C. The absolute maximum power dissipation is 155 mW when given a maximum ambient temperature of 55°C. Input voltage, output voltage or load current limits can also be determined by substituting known values in Equation 5-2 and Equation 5-3. 5.3 Layout Considerations The primary path for heat conduction out of the SC-70 package is through the package leads. Using heavy, wide traces at the pads of the device will facilitate the removal of heat within the package, thus lowering the thermal resistance RθJA. By lowering the thermal resistance, the maximum internal power dissipation capability of the package is increased.
