(Regulated Power Supply) in appliances to give DC power to various electronic circuits.DC supply is used in a variety of power amplifiers and oscillators.0-28V, 6-8A Power Supply Circuit Applications Because of all of these characteristics, these ICs are commonly employed in a wide range of applications. When compared to fixed voltage regulators, it has internal current limiting, thermal shut down, and more line and load regulation. This IC is simple to operate, and the variable supply is provided by simply two resistors. The output voltage of this regulator ranges from 1.2V to 37V at 1.5 amps.
#2N3055 TRANSISTOR RESISTANCE CHECK SERIES#
The 3 pin series adjustable voltage regulator is the LM317. The output will be 100 ohm/1 watt if you use a 100 ohm/1 watt potentiometer current is limited 3 Amps at 47 ohms and 1 Amp at 100 ohm. The maximum current allowed at the output is set with Pot RV2. To get greater current, 2N3055 transistors are employed. Three diodes, D7, D8, and D9, are used to achieve 0V at the output. The LM317 voltage regulator’s minimum output voltage is 1.2V. Pot RV1 allows us to adjust the output voltage from 0 to 28 volts. Capacitor C1 has a rectified voltage of roughly 42.30V (30 volt *SQR2 = 30v *1.41 = 42.30).Īs a result, we must use all of the capacitors in the circuit that are rated at 50 volts. Although the LM317 voltage regulator safeguards the circuit from overheating and overload, the power supply circuit is protected by the Fuses F1 and F2.
