SLG51000
PMIC with High PSRR, Low Noise, Multi-Output LDOs
and Integrated Load Switches
General Description
SLG51000 contains seven compact and customizable low dropout regulators and is designed for
high performance camera modules and other small multi-rail applications.
Two integrated LDOs are optimized to meet the requirements of high-performance analog circuits.
They provide 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.
Two LDOs can be configured to operate as load switches which are optimized to meet the
requirements of low RON. By using efficient DC-DC switching regulators upstream in conjunction with
SLG51000’s linear regulators and load switches 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. SLG51000 has an I2C-compatible
interface for flexible power control. SLG51000 is available in a small 20-pin WLCSP package with a
wide ambient operating temperature range of -40 °C to 85 °C.
