XC6901 Series
200mA Negative Voltage Regulator with ON/OFF Control
ETR03043-007
■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_L) will be discharged via the internal auto-discharge switch and as a result the -V_OUT pin
quickly returns to the V_SS 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.
