PMU is designed to supply integrated circuits with stable and precise voltage. 055UMC_PMU_01 is a library including RS block and 4 LDOs: LDO1 to supply digital circuits; LDO2 and LDO3 to supply analog circuits; LDO4 to supply flash memory. Each of LDO1-LDO4 has an option of choosing load current from 1mA to 50mA. LDO1 operates in two modes: “Full Power” from 1mA to 50mA load current and “Low Power” at 1µA load current to save battery charge if high performance of the system is not required.
