General Description
The GS7131 can deliver up to 5A of continuous
output current with a typical dropout voltage of
only 250mV 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.
The GS7131 allows the use of low-ESR ceramic
capacitor as low as 10uF. Moreover the IC
provides good performance on both line transient
response and load transient response.
The GS7131 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 GS7131 is available in PSOP-8 package.
