ABSTRACT:
A constant-voltage regulated power supply circuit has an input circuit and an output circuit. The sense circuit includes a programmable sense circuit that further includes a divider network with a plurality of selectable tap points and a multiplexer having a plurality of inputs and an output with each tap point being connected to an individual input of the multiplexer. A controllable pass element is operatively connected in the power supply circuit between the input circuit and the output circuit. A comparator connected to receive inputs from a selected tap point and a reference voltage generating circuit provides an output to control the controllable pass element.
