XC6901 Series

200mA Negative Voltage High Speed Regulator with ON/OFF Control

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.

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.
