Description

The R5326 Series are CMOS-based auto mode switching dual LDO regulators featuring 150mA output. In auto switching mode, the operation can switch automatically to a fast response mode or a low power mode of the ECO function according to output current. (Automatic switching to fast response mode under IOUT > 3mA conditions or to low power mode under IOUT < 0.6mA conditions.)

In low power mode, supply current is as low as 5.5µA. In fast response mode, ripple rejection is 70dB and noise is low. R5326 requires neither ECO pin for switching mode nor microcontroller pin. R5326 supports low voltage, featuring input voltage from 1.4V and output voltage from 0.8V. Standby mode and auto-discharge function are also available.
