9 Volt 2 Amp PSU Single IC Regulator Power Supply

Notes

There is little to be said about this circuit. All the assignment is done by the regulator. The 78S09 can bear up to 2 amps connected achievement whilst advancement a low babble and actual able-bodied adapted supply.

The ambit will assignment after the added components, but for about-face polarity aegis a 1N5400 diode is provided at the input, added cutting actuality provided by C1. The achievement date includes C2 for added filtering, if powering a argumentation ambit than a 100nF capacitor is additionally adorable to abolish any aerial abundance switching noise.

9 20 Volt amplifier circuit

For this time I will post the scheme following an amplifier of the IC KA2203, SN16975, TBA820, UL1482P. Which has 4 Watt power output with 4 Ohm impedance. At least 8 Volt supply voltage and a maximum of 20 volts.

Part List

R1 = 100K

R2 = 56R

R3 = 56R

Use 1/2 W resistor

C1 = 47uF

C2 = 100uF
C3 = 100uF
C4 = 470uF
C5 = 470pF
C6 = 0.22uF
C7 = 100uF
U1 = KA2203 , SN16975, TBA820, UL1482P
