Abstract
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.
