5 volts high current power supply using 7805 voltage regulator


Posted on Feb 5, 2014

This power supply electronic circuit is a high current 5 volts power supply circuit that use a 7805 voltage regulator and some classic electronic components. T1 acts as a current limiter. Once the voltage on R2 + R3 is greater than 0. 6 0. 7 V, the transistor opens, which will reduce to zero the current in the base of T2. Voltage from which enters i

n operation the protective circuit is given by the sum of drops voltage on the R2 and R3. Resistors R3 and R4 form a voltage divider on T2.
