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.

■PIN
CONFIGURATION
* The dissipation pad for the USP-6C package should be solder-plated in recommended mount pattern and metal masking to enhance
mounting strength and heat release. If the pad needs to be connected to other pins, it should be connected to the -V
IN
(No. 3) pin.
