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.
