GSS1120
Dual 1A Low Dropout Positive Regulator
Description
The GSC1120 series are low dropout positive regulator with minimum of 1A output current capability. The
product is specifically designed to provide well-regulated supply for low voltage IC applications such as high
speed bus termination and low current 3.3V/2.5V or 3.3V/1.8V logic supply. GSC1120 series and guaranteed
to have <1.3V dropout at full load current making it ideal to provide well regulated outputs dual channels with
up to 18V input supply.

Function
GND 1/2 Ground
3.3V (Vout1)
The output of the regulator.
A minimum of 10 F capacitor
2.5V/1.8V (0.15 ESR 20 ) must be connected
(Vout2)
from this pin to ground to insure stability.
B: ch1=3.3V, ch2=1.8V
Applications
Ô¦PC peripheral
Vin 1/2
The input pin of regulator.
Typical a large storage capacitor
(0.15 ESR 20 ) is connected form
this pin to ground.
