RT8036

One Step Down DC/DC Converter and Four Linear

Regulators with Individual On/Off Control

General Description

The RT8036 is an integrated power management unit which

integrates one 600mA high efficiency step down DC/DC

converter and four low dropout voltage regulators with

300mA current capability for each regulator.

The RT8036 is optimized for sub block power requirement

solution. The individual on/off control for each device can

provide flexibility for different power on sequence. Four

linear regulators provide high PSRR output and are suitable

for both analog and digital power.

The RT8036 is available in the WQFN-20L 3x3 package

that is suitable for portable device.

Features

Four Low Noise LDOs for Up to 300mA

One High Efficiency Synchronous Buck Up to 600mA

Output

Individual On/Off Control for Each Output

Small 20-Lead WQFN Package

RoHS Compliant and Halogen Free

Applications

Smart Handheld device

Cellular phone
