Abstract:
A low-dropout (LDO) regulator includes a voltage reference circuit to provide a reference voltage, a pass device including an input terminal coupled to a voltage input, an output terminal to provide an output voltage and a control terminal, and an error amplifier including a first amplifier input for receiving the reference voltage, a second amplifier input, an amplifier output coupled to the control terminal of the pass device. Additionally, the LDO regulator includes a feedback circuit including a feedback input coupled to the output terminal of the pass device and a feedback output coupled to the second amplifier input to provide a feedback signal. The LDO regulator further includes a control circuit including a non-volatile memory to store configuration data to control operation of the voltage reference circuit, the pass device, the error amplifier, and the feedback circuit to produce the output voltage.
