XC6222 Series

700mA High Speed LDO Regulator

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, 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.

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.

QuestionWhat is the standby current?

The current that flows through the IC in the standby mode. The standby mode means the state where the IC has been turned off by the CE function.
