G9161  
400mA High PSRR, LDO Regulators  
Features  
General Description  
„
„
„
„
Low, 90µA No-Load Supply Current  
The G9161 series is a low supply current, high PSRR,  
Guaranteed 400mA Output Current  
PSRR=65dB @ 120Hz; 55dB @ 1kHz  
Over-Temperature Protection and Short-Circuit  
Protection  
and low dropout linear regulator that comes in a  
SOT-89, SOT-223, TO-252 and SOP-8 with Power  
PAD package. The supply current at no-load is 90µA.  
Operating voltage range is from 2.50V to 5.50V. The  
over-current protection limit is set at 550mA typical. An  
over- temperature protection circuit is built-in in the  
Device to prevent thermal overload.  
„
„
Output Voltage: 1.20V~5.00V (G9161-XXX)  
Stable with low cost ceramic capacitors  
The output voltage range is from 1.2V to 5.0V.

Detailed Description  
Over Current Protection  
Power-Supply Rejection and Operation from  
Sources Other than Batteries  
The G9161 uses a current sense-resistor to monitor  
the output current. A portion of the PMOS output tran-  
sistor’s current is mirrored to a resistor such that the  
voltage across this resistor is proportional to the output  
current. Once the output current exceeds limit thresh-  
old, G9161 would be protected with a limited output  
current. Further more, when the output is short to  
ground, the output current would be folded-back to a  
less limit.  
The G9161 is designed to deliver low dropout voltages  
and low quiescent currents in battery powered sys-  
tems. Power-supply rejection is 65dB at low frequen-  
cies. As the frequency increases above 20kHz, the  
output capacitor is the major contributor to the rejec-  
tion of power-supply noise.  
When operating from sources other than batteries,  
improve supply-noise rejection and transient response  
by increasing the values of the input and output ca-  
pacitors, and using passive filtering techniques.  
Over Temperature Protection  
To prevent abnormal temperature from occurring, the  
G9161 has a built-in temperature monitoring circuit.  
When it detects the temperature is above 145°C, the  
output transistor is turned off. When the IC is cooled  
down to below 120°C, the output is turned on again. In  
this way, the G9161 will be protected against abnor-  
mal junction temperature during operation.  
Load Transient Considerations  
The G9161 load-transient response graphs show two  
components of the output response: a DC shift of the  
output voltage due to the different load currents, and  
the transient response. Typical overshoot for step  
changes in the load current from 10mA to 300mA is  
8mV. Increasing the output capacitor's value and de-  
creasing its ESR attenuates transient spikes.  
Applications Information  
Capacitor Selection and Regulator Stability  
Normally, use a 1µF capacitor on the input and a  
4.7µF capacitor on the output of the G9161. Larger  
input capacitor values and lower ESR provide better  
supply-noise rejection and transient response. A  
higher- value input capacitor (10µF) may be necessary  
if large, fast transients are anticipated and the device  
is located several inches from the power source.  
Input-Output (Dropout) Voltage  
A regulator's minimum input-output voltage differential  
(or dropout voltage) determines the lowest usable sup-  
ply voltage. In battery-powered systems, this will de-  
termine the useful end-of-life battery voltage. Because  
the G9161 use a P-channel MOSFET pass transistor,  
their dropout voltage is a function of RDS(ON) multiplied  
by the load current.
