General Description

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 Inter-

nal n-channel MOSFETs. The output voltage is

adjustable from 0.8V to the voltage that is very

close to VIN.

The GS7103 allows the use of low-ESR ceramic

capacitor as low as 10uF. Moreover the IC

provide good performance on both line transient

response and load transient response.

The GS7103 provides foldback over current limit

and thermal shutdown to prevent the linear

regulator

from

damage.

Built-in

soft-start

minimizes stress on the input power source by

reducing capacitive inrush current on start-up.

During start-up, POK remain low until the output

reaches 92% of its rating value.

The GS7103 is available in PSOP-8 package or

TDFN10-3x3 package.
