Abstract
A low dropout voltage regulator includes an error amplifier, a voltage divider, and a voltage reference/amplifier circuit. The error amplifier has first and second input terminals, a power supply terminal for receiving an input voltage, and an output terminal for providing a regulated output voltage. The voltage divider provides a feedback voltage as a predetermined fraction of said regulated output voltage. The voltage reference/amplifier circuit provides a first voltage to said first input terminal of said error amplifier that varies inversely with variations of said feedback voltage, and provides a second voltage to said second input terminal of said error amplifier that varies by substantially the same amount over temperature as variations in said first voltage.
