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.
