Use of Darlington at output boosts power rating of standard opamp voltage regulator circuit. Article gives step-by-step design procedure. With μA741 opamp, circuit gives good regulation along with short-circuit protection. AC ripple is less than 2 mV P-P. Required input of 30V is obtained from conventional full-wave bridge rectifier with capacitor-input filter.-C, Brogado, IC Op Amps Simplify Regulator Design, EDN/EEE Magazine, Jan. 15, 1972, p 30-34.
