A trimmable voltage regulator feedback network is arranged as a voltage divider: series-connected resistors are connected between the divider tap and the regulator's output voltage and a fixed resistance is connected between the tap and ground. Severable links are connected across at least two resistors above the tap to allow the regulator output voltage to be trimmed in linearly independent increments with each severed link, thereby simplifying the task of determining which links to sever to attain a desired output voltage. A trimmable resistance is inserted between the divider tap and the circuit being driven to enable the impedance of the network to be adjusted. A regulator including the novel feedback network can provide a temperature-compensated output over the full range of selectable output voltages.
