Claim:
1. A low power driver circuit comprising: a first current mirror coupled to a high voltage rail, the first current mirror having a first output terminal; a second current mirror coupled to a low voltage rail, the second current mirror having a second output terminal; a first diode coupled between the first output terminal of the first current mirror and the low voltage rail, wherein the first current mirror supplies a regulated voltage to the first diode; and a first transistor having first, second and third terminals, the first and second terminals being coupled between the high voltage rail and the output terminal of the second current mirror, the third terminal being a gate terminal that is coupled to the first diode and the first output terminal of the first current mirror, wherein an output voltage is available from the driver circuit that is less than the voltage on the high voltage rail.
