POWER SUPLY CIRCUIT DIAGRAM

The ambit is based about the 7805 voltage regulator. It has alone 3 access (input, achievement and ground) and it provides a anchored output. The aftermost two digits of the allotment cardinal specify the achievement voltage, eg. 05, 06, 08, 10, 12, 15, 18, or 24. The 7800 alternation provides up to 1 amp amount accepted and has on-chip dent to shut bottomward the regulator (rather than alarming out) if any attack is fabricated to accomplish it alfresco its safe operating area. (If this happens to you, let the dent air-conditioned bottomward & attach the heatsink.)

It can be apparent that there are in actuality two abstracted circuits in this ability supply. One 7805 is anon affiliated as a anchored 5V regulator. The additional 7805 has a resistor affiliate arrangement on the output. A capricious 500R potentiometer is acclimated to alter the achievement voltage from a minimum of 5V up to the best DC voltage depending on the ascribe voltage. It will be about 2V beneath the ascribe DC voltage.)

The capacitor beyond the achievement improves brief response. The ample capacitor beyond the ascribe is a clarify capacitor to advice bland out ripple in the rectified AC voltage. The beyond the clarify capacitor the lower the ripple.
