Constant voltage source with 5A load current

Published:2011/4/10 22:56:00 Author:Nicole | Keyword: constant voltage source | From:SeekIC

Adopted operation amplifier can obtain constant voltage source with high amplification factor and large load current, when the circuit parameter has great change, the output voltage still have high precision. The output current limit is undertaken by T3, T4 and positive feedback circuit which is composed of operation amplifier. The technical parameters of this circuit: input voltage: UE=7~18V; maximum output voltage: Umax=UE-2V; maximum load current: Imax=5A.
