3A Switching Voltage Regulator based LM317HV


Posted on Feb 6, 2014

Above circuit diagram is a easy, simple and cheap switching voltage regulator which has capability to deliver adjustable voltage output range of 1. 8V to 32V and static electric current of 3A. This regulator use adjustable regulator IC of LM317HV and a power PNP transistor of 2N3792. Positive voltage regulator circuit with PNP Boost transistor The

IC8211 presents the voltage reference and regulator amplifier, while Q1 will be the series pass transistor. R1 defines the output current of the IC8211, while C1 and C2 present loop stability and as well act to suppress feedthrough of input transients to the output supply. R2. This is the circuit diagram of automatic light controller which use 78xx voltage regulator IC series. The voltage regulator ICs deliver a constant output voltage, as against a extensively fluctuating input supply, when the common terminal is grounded. Any voltage about zero volt (ground) interconnected within the common terminal is added to the output voltage. . By default, the regulator ID 78xx series will give maximum current output 1A - 1. 5A. To increase the current output of this regulator, you may consider this circuit. Parts list: R1, R2 = 4. 7 K C1, C2 = 4700 uF / 16V C3 = 47, 000 uF / 35V D1, D2, D3 = 1N5401 ( 3 Amp. Powered with solar panel, the circuit will give you 5V pure regulated DC voltage. The circuit is made up of an oscillator transistor as well as a regulator transistor. The solar panel charges the battery when sunlight is bright enough to generate a voltage above 1. 9v. A diode is necessary between the panel and also. This is power supply circuit which have 2 output that are static output and adjustabled output. The static output is stabled and regulated output. The circuit is based around the 7805 voltage regulator. It has only 3...
