General Description
The GS7155NV can deliver up to 3A of output
current with a typical dropout voltage of only
240mV 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 GS7155NV 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 GS7155NV 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 GS7155NV is available in PSOP-8 package.
