Low dropout voltage regulators circuits

Power Supply circuits | By: Diagram mania

I have a 6V battery, but it needs to be applied to digital circuits that used to 5 volt regulated. In first, I will reduce this voltage with a single resistor, but the load current is not constant. The other way to use is a second, I would use 2 x 1N5402 diodes to connected […]
