R1163 Series
Manual ECO Mode Shift 150mA Voltage Regulator with Reverse Current Protection
The R1163 Series are CMOS-based manual mode switching LDO regulators with ECO pin featuring 150mA output. By inputting control signals to the ECO pin, the mode of the regulator can be switched to low power mode or fast response mode, thus making both active and sleep modes available for the system. The built-in reverse current protection circuit prevents the current flow from VOUT to VDD when VOUT is higher than VDD. This feature makes the product ideally suited for backup circuit. Standby mode and auto-discharge function are also available.
