R1162x Series
150mA LDO with ECO pin
The R1162x Series are CMOS-based LDO regulators with ECO pin featuring 150mA 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. The version with the auto-discharge function is also
available. Ceramic capacitors can be used.
