R1163x Series
Manual Mode Shift 150mA LDO with Reverse Current Protection
The R1163x 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 (see Selection Guide). Ceramic capacitors can be used.
∗) R1163N Series are suitable for automotive applications too. Please refer to our "Car Electronics Products Catalog" or contact us.
