Easy power supply 0-15V , 0-1A

Power Supply circuits | By: Diagram mania

This is easy circuit power supply, variable regulator adjustable voltage output 0V to 15V and Current adjust 0A to 1Amax. Use normal electronics part. TR1 provides a constant current to a bank of three zener diodes, thus maintaining a constant voltage independant of supply voltage variations. The resistor Rx is used to sense the PSU […]

TTL Power Supply with ‘Crowbar’ protection by 7805 and SCR

Power Supply circuits | By: Diagram mania

Power supplies that are intended to be used with TTL logic circuitry must guard against over-voltage, which can destroy TTL chips very rapidly. The duration of over-voltage that can destroy TTL chips is much too brief to trigger any conventional fuse, so that only other semiconductor circuits can play any useful part in protecting a […]

Low Drop-Out Regulators with IC MIC29152

Power Supply circuits | By: Diagram mania

A major drawback of the 317T and similar standard regulators is that 1.7–2 volts are lost from the 12V supply, so the fan can only run up to about 85% of its full speed and flow rating. Although this site is aimed at keeping noise down, there may be occasions when you want to turn […]
