XC6901 Series
200mA Negative Voltage Regulator with ON/OFF Control
■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 (C
quickly returns to the V
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.
■APPLICATIONS
●CCD power supplies
●LCD Modules
●Op-Amp power supplies
●Digital still cameras
●Battery powered equipment
