ABSTRACT:
A voltage regulator (10) is provided. A first bipolar transistor (24) has an emitter connected to a first node (NODE 6) and a base connected to a second node (NODE 5). A second bipolar transistor (30) is scaled N:1 with respect to the first bipolar transistor (24), N greater than one. The second bipolar transistor (30) has an emitter, a base, and a lateral collector. The base is connected to the second node (NODE 5). A first resistor (20) is connected between the first node (NODE 6) and an output node (NODE 2). A second resistor (32) is connected between the first node (NODE 6) and the emitter of the second bipolar transistor (30), and a third resistor (22) is connected between the first node (NODE 6) and a ground node (GND). A current sensing amplifier (12, 14, 34, 38 and 40) has a first input node (NODE 7) connected to the lateral collector of the first bipolar transistor (24) and a second input node (NODE 8) connected to the lateral collector of the second bipolar transistor (30). The current sensing amplifier (12, 14, 34, 38 and 40) is operable to match emitter currents through the first and second bipolar transistors (24 and 30). The voltage regulator (10) is operable to produce a temperature stable output voltage level (V.sub.OUT) at the output node that is settable to a desired voltage level.
