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.

From the 78XX Voltage Regulator Integrated Circuit series, 7806 IC is used to regulate the output voltage to 6 Volts (Fixed constant value with minimal fluctuations). Many chip manufacturing companies provide this IC with different output current and over-current protection characteristics. Each IC may have different output current characteristics varying from 1 Amp to 1.5 Amps. Refer datasheets to know which one you will need to design your 6V regulator.

The 7806 IC is also available in T)-3, TO-252, TO-92 & SO-8 packages.

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.

  7. i just want to know the calculation of the 6 Volt Regulator using IC 7806 u’ve post .. will u please send me the complete calculation to this email add… cabalanromeojr@yahoo.com
    tnx…. asap.

  8. please i need information/circuit diagram on fire detection and fire suppression systems in an aircraft specifically in the cargo compartment. thanks

  9. thanks 4 for supports .I’m interested in electronics and i want to build a battery charger for 5v and 250mA please send to me circuits and calculation.I’m looking forward .

  10. Hi Sir, could You please assist by sending me a circuit diagram with the components on how to build a power supply that will power a 6volts 20watts bulb.
    Thanks

    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)

  12. Manjunath

    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

    please i need full detail on automatic voltage regulator, i am a final year student and project is base on construction of AVR. please i want send full detail to me through my email(adedayo_dml@yahoo.com) thanks

  16. 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.
