15-V 1-A Regulated Power Supply

Here is incredibly straightforward build power provide Electronic Circuit Project of 15-V 1-A Regulated Power provide circuit. the availability receives - twenty V from the rectifier/filter that is fed to the collector of the Darlington pnp pass semiconductor, a TIP105. the bottom drive to the TIP105 is provided through electrical device R5. the bottom of the TIP105 is driven from Vz terminal at pin nine, that is that the anode of a six.2-V zener diode that connects to the electrode of the uA723 output management semiconductor.

15-V 1-A Regulated Power provide Circuit Diagram:

The method of providing the positive feedback required for foldback action is shown. This technique introduces positive feedback by increased current flow through resistors R1 and R2 under short-circuit conditions. This forward biases the base-emitter junction of the 2N2907 sensing transistor, which reduces base drive to the TIP105
