LP3970
Power Management Unit for Advanced Application
Processors
General Description
The LP3970 is a multi-function, programmable Power Man-
agement Unit, designed especially for advanced application
processors. The LP3970 has been optimized for low power
handheld applications PMU provides 11 low dropout, low
noise linear regulators, two DC/DC magnetic buck regula-
tors, a back-up battery charger and 4 GPO’s. A high speed
serial interface is included to program individual regulator
output voltages as well on/off control.
