6 Volt Regulator using IC 7806

Description.

Here is the elementary 6V 1A power supply circuit using 7806 IC. The 7806 three-terminal positive voltage regulator is available in the TO-220/D-PAK package making them useful in a wide range of applications. 7806  employs internal current limiting, thermal shut down and safe operating area protection, making it essentially indestructible. If proper heat sinking is provided, it can deliver over 1 ampere output current.

Notes .

  • If 2A bridge is not available make one with four 1N 4007 diodes.
  • Fit a proper heat sink with 7806 if your circuit draws  more than 400mA current.

    Hi Shruthi the IC is a fixed 8 volt series pass regulator input for the IC can be between 11volt and 35volt. It has built in voltage reference, comparators, current sense limit, thermally safe area of operation and series pass transistors. kindly refer Motorola datasheet and its internal drawings.

    Hi GBENGA you can use the same circuit with additional PNP transistors. you require 6 volt at 4amps you can use the following principle as done for 12 volt.

    Hi Manjunath you can use this circuit, instead of transformer you can use your generator. (Pl check the circuit current capability as the mobile phone requires around 400mA at 6 volts)

    Dear Sir,

    I am using Generator as as Photocopier Stepper Motor, it is generating upto 18 volts AC, i converted it to DC using Bridge rectifier it showing 16 volts DC and now i wanted to reduce it for 6 volts (For mobiling battery charging). Is it possible from this circuit.
    Please reply me i am very much interested
    Thanking you,
    With warm regards

    thanks
    i just want to know how to control current o/p.
    cos i need .5A & .21A o/p, please post the calculations..
    thank u

      First of all 7806 alone can’t deliver more than 1A. You need extra circuitry to boost the current capability.Using a series pass transistor is a good option.
