The ESR of the output capacitor is critical to the transient spike. A larger capacitance along with smaller ESR results in a smaller spike. Similar to any low dropout regulator, the external capacitors used with the PAM3101 must be carefully selected for regulator stability and performance. Shutdown Input Operation A capacitor C IN of more than 1μF can be employed in the input pin, while there is no upper limit for the capacitance of C IN. Please note that the distance between C IN and the input pin of the PAM3101 should not exceed 0.5 inch. Ceramic c a p a c i t o r s a r e s u i t a b l e f o r t h e PA M 3 1 0 1 . Capacitors with larger values and lower ESR (equivalent series resistance) provide better PSRR and line-transient response. 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. Internal P-Channel Pass Transistor The PAM3101 features a 0.75 Ω P-Channel MOSFET device as a pass transistor. The PMOS pass transistor enables the PAM3101 to consume only 65 μ A of ground current during low dropout, light-load, or heavy-load operations. This feature increases the battery operation life time. 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 > 2.2 μ F with ESR>5mΩ ensures stability. Input-Output ( Dropout ) Voltage A 10nF bypass capacitor connected to BYP pin is suggested for suppressing output noise. The capacitor, in series connection with an internal 200k Ω resistor, forms a low-pass filter for noise reduction. Increasing the capacitance will slightly decrease the output noise, but increase the startup 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 batterypowered systems, this will determine the useful end-of-life battery voltage. Load Transient Considerations Current Limit and Short Circuit Protection C u r v e 1 0 o f t h e PA M 3 1 0 1 l o a d - t r a n s i e n t 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 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. Power Analog Microelectronics , Inc www.poweranalog.com 09/2008 Rev 1.4 12 PAM3101 300mA High PSRR Low Dropout CMOS Linear Regulator Thermal considerations based on the standard JEDEC 51-3 for a singlelayer thermal test board, the maximum power dissipation at T A=25°C can be calculated by following formula: Thermal protection limits power dissipation in the PA M 3 1 0 1 . W h e n t h e j u n c t i o n t e m p e r a t u r e 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. P D(MAX)= (125°C-25°C)/250=0.4W P D(MAX)= (125°C-25°C)/180=0.55W SOT-23 SOT-89 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 I N =3.3V, the output current I O=300mA and the case temperature T A=40°C measured by a thermalcouple during operation, the power dissipation for the Vo=2.8V version of the PAM3101 can be calculated as: For continuous operation, the junction temperature should be maintained below 125°C. The power dissipation is defined as: P D= (V IN-V OUT)*I O+V IN*I GND 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: P D=(3.3V-2.8V)*300mA+3.3V*70 μ A≌150mW And the junction temperature, T J , can be calculated as follows: T J = T A+P D*θ JA T J = 40°C+0.15W*250°C/W =40°C+37.5°C =77.5°C<T J(MAX) = 125°C P D(MAX) = (T J(MAX)-T A)/θ JA Where T J(MAX) is the maximum allowable junction temperature 125°C, T A is the ambient temperature and θ JA is the thermal resistance from the junction to the ambient. For this operating condition, T J is lower than the absolute maximum operating junction temperature, 125°C, so it is safe to use the PAM3101 in this configuration. For example, as θ JA is 250°C/W for the SOT-23 package and 180°C/W for the SOT-89 package Power Analog Microelectronics , Inc www.poweranalog.com 09/2008 Rev 1.4 13 PAM3101 300mA High PSRR Low Dropout CMOS Linear Regulator Ordering Information PAM3101 X X X xxx Output Voltage Number of Pins Package Type Pin Configuration Pin Configuration A Type Package Type Number of Pins Output Voltage A: SOT-23 A: 3 475: 4.75V E Type 1.
