车规 ET5907
General Description
The ET5907 is CMOS-based low-dropout, low-power linear regulator. It’s a 7-channel integrated LDOs for camera applications. Two channels offering max 1200mA with NMOS pass transistor, five channels offering max 400mA with PMOS pass transistor. ET5907 include 1000kHz high speed I2C interface, the function setting is flexible such as Under voltage lockout (UVLO), power sequence, output voltage, output discharge, current limit per channel. The chip enable control support EN pin control and I2C control.
The ET5907 is available in 20-bump, 0.35 mm pitch, Wafer-Level Chip-Scale Package (WLCSP).
