General Description

SLG51001 contains six compact and customizable low dropout regulators and is designed for high

performance camera modules and other small multi-rail applications.

The LDO_HP is optimized to meet the requirements of high-performance analog circuits. It provides

very low output voltage noise characteristics of 13 µV (rms) in addition to high PSRR of 81 dB at

1 MHz and tight output voltage accuracy of ±1 % over temperature.

The 1 A capable LDO_LV can be configured to operate as a load switch which is optimized to meet

the requirements of low RON. By using efficient DC-DC switching regulators upstream in conjunction

with SLG51001

’s linear regulators and load switch downstream, applications can leverage the best

characteristics of each to simultaneously achieve low power, low noise, and low voltage dropout,

respectively.

Built-in safety protection such as under-voltage lockout, over-temperature protection, and current limit

ensures that the ICs are operating under nominal conditions. SLG51001 has an I2C-compatible

interface for flexible power control. SLG51001 is available in a small 16-pin WLCSP package with a

wide ambient operating temperature range of -40 °C to 85 °C.
