Abstract

A mobile communications device () includes a plurality of LDOs () for supplying a stable voltage to various circuits on the device. In a normal mode, the LDO's main bandgap voltage source () supplies a voltage to a main amplifier (). During deep sleep mode, sleep logic () places the LDOs in a sleeping state, where a low current sleep bandgap voltage source () supplies a voltage to a smaller, sleep amplifier (), which maintains a charge on capacitors () for a fast transitions to a full ON state.
