The AT73C237 power management unit (PMU) is compatible with a 5-V input supply and generates four regulated output voltages, with output current up to 70 mA.
The device integrates four LDO regulators, three are programmable from 1.2 to 2.75 V, and one 1.8-V regulator for backup battery and capacitor recharging. It integrates a two wire interface and allows a microcontroller to program the variable LDO output voltages. ($1.65 ea/100,000 available now.)
