General Description
The GS7116 is a high performance regulator
which can deliver up to 500mA of continuous
output current with a typical dropout voltage of
only 200mV using internal p-channel MOSFETs.
The GS7116 allows the use of low-ESR ceramic
capacitor as low as 4.7uF. Moreover the IC
provides good performance on both line transient
response and load transient response.
The GS7116 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.
The GS7116 is available in the TSOT-23-5
,SOT-23-5 and TDFN6-2x2 packages.
