Low dropout regulators

摘要

A voltage regulator circuit includes: an output transistor MPX coupled between a voltage supply node VCC and an output node VOUT; an amplifier A1 coupled to the output transistor MPX for controlling the response of the output transistor MPX; feedback circuitry R1 and R2 connected between the output node VOUT and the amplifier A1, the feedback circuitry R1 and R2 providing feedback to the amplifier A1; and a pull-down circuit PD1 coupled to the output node VOUT. <IMAGE>
