Abstract
A low dropout regulator includes a proportional-to-absolute-temperature (PTAT) circuit, an amplification circuit, and an output circuit. The PTAT circuit outputs one current, and the amplification circuit outputs one or more currents. The one or more currents are outputted by the amplification circuit based on collector-emitter voltages associated with transistors of the PTAT circuit. Alternatively, the one or more currents are outputted by the amplification circuit based on the current outputted by the PTAT circuit and the collector-emitter voltages associated with the transistors of the PTAT circuit. The output circuit generates one or more output voltages based on at least one of a base-emitter voltage associated with a transistor of the PTAT circuit and a current of the one or more currents outputted by the amplification circuit.
