GENERAL DESCRIPTION

The XC6901 Series is a negative voltage CMOS regulator which includes a reference voltage source, error amplifier, driver

transistor, current limiter and phase compensator.

The CE function enables the circuit to be in stand-by mode by inputting low level signal. In the stand-by mode, the electric

The over current protection circuit will operate when the output current reaches limit current. The thermal shutdown circuit will

operate when the junction temperature reaches limit temperature.
