Reverse Current Protection, 700mA High Speed LDO Regulator

■

GENERAL DESCRIPTION

The XC6222 series is a highly accurate, low noise, high ripple rejection, low dropout, and low power consumption high speed

CMOS voltage regulator. The series consists of a voltage reference, an error amplifier, a driver transistor, a current limiter, a

thermal protection circuit, a reverse current protection circuit and a phase compensation circuit.

The CE function enables the entire circuit to be placed in a stand-by state by inputting a low level signal to the CE pin. In this

Over-current protection and thermal protection circuits are integrated. The protection circuit starts to operate when either output

current reaches the current limit level or junction temperature reaches the temperature limit. With the reverse current

for use in backup power circuits.
