R1160N Series
Manual Mode Shift Low Voltage 200m A LDO
The R1160N Series are CMOS-based Manual mode switching LDO regulators with ECO pin featuring 200m A 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 CE pin can switch the regulator into standby mode. This feature helps to extend the battery life.
