GS7103 Datasheet – 3A Ultra Low Dropout Linear Regulator

This is one of the regulator types.

Part Number: GS7103, GS7103SO-R

Function: 3A Ultra Low Dropout Linear Regulator

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

Manufacturer: 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.

TPS79918 datasheet



The TPS799 family of low-dropout (LDO), low-power linear regulators offers excellent ac performance with very low ground current. High power-supply rejection ratio (PSRR), low noise, fast start-up, and excellent line and load transient response are provided while consuming a very low 40-µA (typical) ground current.

The TPS799 is stable with ceramic capacitors and uses an advanced BiCMOS fabrication process to yield a dropout voltage of typically 100 mV at a 200-mA output. The TPS799 uses a precision voltage reference and feedback loop to achieve an overall accuracy of 2% over all load, line, process, and temperature variations. The TPS799 features inrush current protection when the EN toggle is used to start the device, immediately clamping the current.
