GS2906B
500mA Ultra Low Dropout Regulator
Product Description
The GS2906B is a high performance positive
voltage regulator designed for use in applications
requiring very low input voltage and very low
dropout voltage at 600mA amps. It operates with a
VIN as low as 2.5V, with output voltage
programmable as low as 0.8V. GS2906B has an
enable pin to further reduce power dissipation
while shut down. The enable pin may be tied to VIN
if it is not required for ON/OFF control. The
GS2906B provides excellent regulation over
variations in line, load and temperature.
Vout can be programmed from 0.8V to 5V with two
external resistors. The optimum thermal condition
has to consider the layout placement and
application to achieve its satisfied high output
current requirement.
The GS2906B is SOT-23-5L packages.

Pin Description
Input Voltage. 1uF capacitance should be placed closely to Vin
Reference Ground.
Enable Input. Pulling this pin to “High” turn on the IC, pulling this pin to “Low” turn off the IC.
This is the input to the error amplifier. The ADJ reference voltage is 0.8Vreferenced to
ground.
VOUT
The pin is the power output of the device, connect 2.2uF capacitor to GND.
Vout1.2V, Recommend using 10pF capacitor.
