6 Volt Regulator Circuit

admin May 13, 2010 2 Comments

Circuit Description

The elementary circuit diagram of 6V voltage regulator has been given here. The main part of this circuit is the voltage regulator IC 7806. . This IC 7806 is a three-terminal positive voltage regulator. This IC is suitable for a wide range of applications in voltage regulator circuits. This IC has some advanced features such as internal current limiting, thermal shut down and safe operating area protection. These features make this IC indestructible. At normal conditions with heat sink, this IC can deliver an output current of 1A.

230V AC input is taken through step-down transformer and is rectified using a bridge rectifier circuit. Following this a capacitor filter network is used for filtering the rectifier output. The filtered signal is given to the IC 7806.

Notes

  • Use a good quality PCB to assemble this particular circuit.
  • The IC 7806 is available in the TO-220/D-PAK package.
  • Adequate heat sink should be provided for the IC 7806 if this circuit draws more than 400mA current.
  • Use four 1N 4007 diodes if 2A Bridge is not available for the rectifier circuit.
