5.3 Low Dropout Regulator

A built-in Low Dropout (LDO) Regulator is used to convert the battery or adaptor power for power supply. It also integrates the hardware architecture to control the power-on/off procedure. The built-in programmable LDOs provide power for codec and digital I/O pads. Also, it is used to buffer the high input voltage from battery or adapter. This LDO requires 1 μF bypass capacitor.
