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.
