The LP3972 is a multi-function programmable power management unit (PMU) designed especially for advanced application processors. The LP3972 is optimized for low-power handheld applications and provides six low-dropout low-noise linear regulators, three DC-DC magnetic buck regulators, a backup battery charger, and two GPIOs. A high-speed serial interface is included to program individual regulator output voltages as well as on and off control.

For all available packages, see the orderable addendum at the end of the data sheet.
