General Description
The GS7103 can deliver up to 3A of continuous output current with a typical dropout voltage of only 300mV 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.
