We all are pretty familiar with the 78XX voltage regulator ICs or the adjustable types such as LM317, LM338 etc. Though these regulators are outstanding with their specified functioning and reliability, these regulators have one big disadvantage…. they won’t control anything above 35V. Circuit Operation The circuit presented in the following article introduces a DC […]
