LOW DROPOUT REGULATOR WITH HYSTERETIC CONTROL

摘要

Described is an apparatus comprising: an output stage having an input supply node to receive an input power supply and an output node to provide an output supply to a load; an amplifier to control current strength of the output stage according to the output supply and a reference voltage; and a hysteresis unit to monitor the output supply and operable to control the current strength of the output stage according to a voltage level of the output supply. Described is another apparatus which comprises: a plurality of charge pumps to adjust current strength of the output stage; and a logic unit to monitor the output supply and operable to control the plurality of charge pumps according to a voltage level of the output supply and one or more reference voltages.
