Amp. https://electronicsarea.com/12v-power-supply-using-zener-diode-741-op-amp/ https://electronicsarea.com/12v-power-supply-using-zener-diode-741-op-amp/#respond Wed, 27 Jan 2021 15:19:52 +0000 http://electronicsarea.com/?p=3655 This 12V Power Supply has, as its main characteristic, a low output impedance. This is a very desirable feature in voltage sources and is achieved with a large open loop gain that the operational amplifier has.
