Capacitor Selection and Regulator Stability Load Transient Considerations Shutdown Input Operation Internal P-Channel Pass Transistor Input-Output ( Dropout ) Voltage Current Limit and Short Circuit Protection Similar to any low dropout regulator, the external capacitors used with the PAM3101 must be carefully selected for regulator stability and performance. A capacitor C of more than 1μF can be employed in the input pin, while there is no upper limit for the capacitance of C . Please note that the distance between C and the input pin of the PAM3101 should not exceed 0.5 inch. Ceramic capacitors are suitable for the PAM3101. Capacitors with larger values and lower ESR (equivalent series resistance) provide better PSRR and line-transient response. The PAM3101 is designed specifically to work with low ESR ceramic output capacitors in order to save space and improve performance. Using an output ceramic capacitor whose value is A 10nF bypass capacitor connected to BYP pin is suggested for suppressing output noise. The capacitor, in series connection with an internal 200k resistor, forms a low-pass filter for noise reduction. Increasing the capacitance will slightly decrease the output noise, but increase the start- up time. Curve 10 of the PAM3101 load-transient response on page 10 shows two components of the output response: a DC shift from the output impedance due to the load current change and transient response. The DC shift is quite small due to excellent load regulation of the PAM3101. The transient spike, resulting from a step change in the load current from 1mA to 300mA, is 20mV. The ESR of the output capacitor is critical to the transient spike. A larger capacitance along with smaller ESR results in a smaller spike. The PAM3101 is shut down by pulling the EN input low, and is turned on by tying the EN input to VIN or leaving the EN input floating. The PAM3101 features a 0.75 device as a pass transistor. The P- MOS pass transistor enables the PAM3101 to consume only 65 A of ground current during low dropout, light-load, or heavy-load operations. This feature increases the battery operation life time. A regulator's minimum input-output voltage difference (or dropout voltage) determines the lowest usable supply voltage. The PAM3101 has a typical 300mV dropout voltage. In battery- powered systems, this will determine the useful end-of-life battery voltage. The PAM3101 features a current limit, which monitors and controls the gate voltage of the pass transistor. The output current can be limited to 400mA by regulating the gate voltage. The PAM3101 also has a built-in short circuit current limit. IN IN IN 2.2 F with ESR>5mΩ ensures stability.

Thermal protection limits power dissipation in the PAM3101. When the junction temperature exceeds 150°C, the OTP (Over Temperature Protection) starts the thermal shutdown and turns the pass transistor off. The pass transistor resumes operation after the junction temperature drops below 120°C. For continuous operation, the junction temperature should be maintained below 125°C. The power dissipation is defined as: P = (V -V )*I +V *I The maximum power dissipation depends on the thermal resistance of IC package, PCB layout, the rate of surrounding airflow and temperature difference between junction and ambient. The maximum power dissipation can be calculated by the following formula: Where T is the maximum allowable junction temperature 125°C, T is the ambient temperature and is the thermal resistance from the junction to the ambient. For example, as is 250°C/W for the SOT-23 package and 180°C/W for the SOT-89 package based on the standard JEDEC 51-3 for a single- layer thermal test board, the maximum power dissipation at T =25°C can be calculated by following formula: It is also useful to calculate the junction temperature of the PAM3101 under a set of specific conditions. For example, suppose the input voltage V =3.3V, the output current I =300mA and the case temperature T =40°C measured by a thermalcouple during operation, the power dissipation for the Vo=2.8V version of the PAM3101 can be calculated as: P =(3.3V-2.8V)*300mA+3.3V*70 A 150mW And the junction temperature, T , can be calculated as follows: T= T =40°C+37.5°C =77.5°C<T = 125°C For this operating condition, T is lower than the absolute maximum operating junction temperature, 125°C, so it is safe to use the PAM3101 in this configuration.
