300mA High PSRR Low Dropout CMOS Linear Regulator
Features
General Description
n Low Dropout Voltage: 180mV@300mA
(V O=3.3V)
n Output Voltage Accuracy within ±2%
n Quiescent Current : 65 μ A Typ.
n High PSRR: 70dB@1kHz
n Excellent Line and Load Regulation
n Fast Response
n Current Limiting
n Short Circuit Protection
n Low Temperature Coefficient
n Shutdown Current : 0.5 μ A
n Thermal Shutdown
n Space Saving Package: SOT-23 , SOT-89
and SC70
n Pb-Free Package
The PAM3101 series of positive voltage linear
regulators feature low quiescent current (65 μ A
Typ.) and low dropout voltage, making them ideal
for battery powered applications. Their high
PSRR make them useful in applications where
AC noise on the input power supply must be
suppressed. Space-saving SOT-23, SOT-89 and
SC70 packages are attractive for portable and
handheld applications. They have both thermal
shutdown and current limit features to prevent
device failure from extreme operating conditions.
They are stable with an output capacitor of 2.2 μ F
or greater.

PAM3101
300mA High PSRR Low Dropout CMOS Linear Regulator
Application Information
Capacitor Selection and Regulator Stability
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.
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
& gt; 2.2 μ F with ESR & gt; 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.

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 & lt; 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
