XC6222B28BMR-G

反向电流保护， 700毫安高速LDO稳压器 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 stand-by mode, the electric charge at the output capacitor CL will be discharged by the internal auto-discharge switch, and as a result the VOUT pin will quickly return to the VSS level.
