The figure shows a unit capable of offering different voltages to operate low-voltage appliances from a 12-V battery. Regulators of the LM317 type are current-limiting, short- circuit-proof, and over-heat-proof, although they are still not indestructible. This circuit will provide up to 1.5 A. IC1 should be heatsinked, perhaps by bolting it with an insulating kit to a metal box.
