General Description
The GS7105 can deliver up to 2A of continuous
output current with a typical dropout voltage of
only 220mV 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 GS7105 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 GS7105 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 GS7105 is available in PSOP-8 package or
TDFN10- 3x3 package.
