專利摘要

The present invention provides a programmable low dropout linear regulator using a reference voltage to convert an input voltage into a regulated voltage according to a control signal. The programmable low dropout linear regulator includes an operational amplifier having a negative input coupled to receive the reference voltage, a first transistor having a gate coupled to an output terminal of the operational amplifier and a first source/drain coupled to an output terminal of the regulated voltage, a first impedance coupled between a positive input of the operational amplifier and the output terminal of the regulated voltage, and a second impedance coupled between the positive input of the operational amplifier and a ground. The second impedance includes a second transistor having a gate coupled to receive the control signal.
