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

charge at the output capacitor (CL) will be discharged via the internal auto-discharge switch and as a result the -VOUT pin

quickly returns to the VSS level.

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.
