General Description
The ET5904A is CMOS-based low dropout, low power linear regulator. It’s a 4-channels integrated LDO with I2C control. LDO1 offer up to 1500mA with NMOS pass transistor, LDO2 offer up to 1000mA with NMOS pass transistor, LDO3/4 offer up to 400mA with PMOS pass transistor. ET5904A include 1MHz high speed I2C interface, the function setting is flexible such as power sequence, output voltage, output discharge, current limit per channel. The chip enable control support EN pin control and I2C control. The ET5904A is available in DFN10 (2×2) package.
