9 Volts 2 Ampere Regulator Circuit


Here is the simple 9 Volt 2 amp supply using a single IC regulator, I just need 9v to operator a mic pre-amp in my car.





Its a simple circuit, the regulator 78S09 is the heart of circuit and it can deliver up to 2 amperes continuous output whilst maintaining a low noise and well regulated supply.

This circuit can be make with out extra components but I added a diode IN5400 for reverse polarity protection, C1 provides extra smoothing and C2 for extra filtering, if powering a logic circuit than a 100nF capacitor is also desirable to remove any high frequency switching noise.
