5V_AT_200mA

Published:2009/7/19 21:06:00 Author:Jessie | From:SeekIC

Article gives step-by-step design procedure for developing special opamp regulator when commercial unit meeting desired specifications is not available. Opamp is μA741. Circuit gives good regulation along with short-circuit protection, with less than 2 mV P-P AC ripple. Required input of 20V is obtained from conventional full-wave bridge rectifier with capacitor-input filter.-C.
