ET5907

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The ET5907 is a multi-channel Low Dropout (LDO) linear voltage regulator manufactured by ETEK Microelectronics. It features seven integrated channels designed for complex power management in camera applications. Two high-current channels provide up to 1500mA output with ultra-low dropout, while five additional channels deliver up to 600mA with low noise characteristics. The device supports flexible configuration via a 1000kHz I2C interface, allowing programmable output voltages and sequencing. It includes comprehensive protection mechanisms such as over-temperature, under-voltage lockout, and over-current protection within a compact WLCSP package.
