Multimedia Processors

•

Portable Handheld Products

allow a host controller access to the internal control

registers. The device also features programmable

power-on sequencing. LDO regulators provide high

PSRR and low noise ideally suited for supplying

power to both analog and digital loads.

The device can be configured either as a Sub_PMU

for modules (for example, camera or multimedia

modules) or as a stand-alone PMU that powers the

processor itself.
