CIRCUIT FOR PERFORMING VOLTAGE REGULATION

摘要

A circuit (10, 100) is used to perform voltage regulation. In one embodiment, a voltage regulator (11) is used in conjunction with an output transistor (24) to form a circuit (10) which operates to regulate the voltage drop from a first node (30) to a second node (28). This second node (28) may be used to provide power to circuitry (27). The areas of several transistors (20-25) in circuit (10) may be adjusted so that negative and positive temperature coefficients may be balanced such that the circuit (10) behaves as desired over a range of voltages and temperatures. Note that in one embodiment, circuit (10) is a 2-terminal device.
