The R5328K series are CMOS-based dual output LDO regulators with ECO pin featuring 150mA output. By inputting the control signals to into the ECO pin, the operation can be switched between fast response mode and low power mode of the ECO function according to the output current. In low power mode, supply current is as low as 2.5μA. In fast response mode, ripple rejection is 70dB and noise is low. R5328K supports low voltage, featuring input voltage from 1.4V and output voltage from 0.8V. Standby mode and auto-discharge function are also available (see Selection Guide). Ceramic capacitors can be used.
