General Description
The ET5917 is CMOS-based low-dropout, low-power linear regulator. It’s a 7-channel integrated LDOs for camera applications. Two channels offering max 1500mA with NMOS pass transistor, five channels offering max 600mA with PMOS pass transistor. ET5917 include 1000kHz high speed I2C interface, the function setting is flexible such as power sequence, output voltage, output discharge, current limit per channel. The ET5917 also integrates the fault monitoring features with interrupt indication. The ET5917 is available in WLCSP20(1.8mm×1.544mm,0.35mm pitch), Wafer-Level Chip-Scale Package.
