Sometimes we want to use. high current at a voltage 5 volts.We can do this by using the voltage regulator IC1 positive constant number 7805.
The Q1 and Q2 of circuit will serve to increase current for IC regulator.The R2 acts as the anti-saturation of Q1 and Q2. Without R2 will allow the two transistors do not work.The output current can be from IC1 alone.R1 specify the bias current to IC1.And the current output of you against too much saturated with. The C1 functions in input power filter to smooth.And C2 serves to prevent interference with the pressure to pay out (Vout).

Increase the current IC LM7805

This circuit can help enlarge current of power supply circuit that use Ic regulator so well. you can use other IC 7805,7809,IC-7812,and IC7815.
Q1 is BFX88 or Equivalent
Q2 is BD132 or Equivalent
