GS7103 Datasheet – 3A Ultra Low Dropout Linear Regulator

Part Number : GS7103, GS7103SO-R

Function : 3A Ultra Low Dropout Linear Regulator

Package : PSOP-8 package, TDFN10-3×3 package

Manufacturers : GStek ( Green Solution Technology )


GS7103 Regulator


The GS7103 can deliver up to 3A of continuous output current with a typical dropout voltage of only 260mV using internal n-channel MOSFETs. The linear regulator uses a separate VDD supply to power the control circuitry and drive the Internal n-channel MOSFETs. The output voltage is adjustable from 0.8V to the voltage that is very close to VIN.
