General Description

        The ET5914 is a 4 channels CMOS-based low-dropout, low-power high performance linear regulator with I2C control. LDO1 offering 1000mA with NMOS pass transistor, LDO2, LDO3 and LDO4 offering 300mA with PMOS pass transistor. ET5914 include 1MHz high speed I2C interface, the function setting is flexible such as working mode, power sequence, output voltage, output discharge, current limit per channel. The chip enable control support EN pin control and I2C control.

        Each LDO of ET5914 can be set to load switch mode. LDO1 can be set as 1.2V to 3.3V load switch, LDO2/3/4 can be set as 1.5 to 5.5V load switch.

        The ET5914 is available in small Package: WLCSP-16 1.44mm×1.38mm
