R1160x Series
Low Voltage 200mA LDO with ECO pin
The R1160x Series are CMOS-based LDO regulators with ECO pin featuring 200mA output. By inputting control signals from 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.
