LM317 LM338 LM350 Current Regulator Calculator and ... LM317 LM338 LM350 Current Regulator Circuits The following circuits show some of the basic uses of the LM317 LM338 LM350 series of voltage regulators when configured as a current regulator or constant current source (CCS). Need a Current Regulator? Use a Voltage Regulator! Most op amps are not designed for high output current, so a linear regulator based circuit allows you to avoid the output current limitations of typical op amps. Regulator ICs incorporate overtemperature protection. Linear regulators offer greater tolerance of large input voltages and high power dissipation. Current regulators tpub The purpose of a current regulator is to provide a constant current regardless of changes in the input voltage or load current. The schematic shown in figure 4 42 is that of a circuit designed to provide a constant current of 400 milliamperes. JFET Current Regulator | Discrete Semiconductor Circuits ... An interesting application of this current regulator circuit is the so called constant current diode. Described in the “Diodes and Rectifiers” chapter of volume III, this diode isn’t really a PN junction device at all. Instead, it is a JFET with a fixed resistance connected between the gate and source terminals: 12 V High current regulator Electronic Circuits and ... 12 V High current regulator. Description. This voltage regulator circuit can deliver up to 3A at 12V output voltage. The circuit can be employed on occasions when a current of more that 3A is demanded for regulator. IC regulators of such high current rating are pretty hard to find. The transformer T1 steps down mains voltage,... 0 30V 20A High current adjustable voltage regulator circuit If you are looking for a high current Adjustable voltage regulator circuit. This may be a better choice for you. It can give the output current 20A or 400watts and can adjust the voltage of 4 to 20V—or apply to 0 to 30V easily. It is good quality, excellent performance and durable with PCB.

Typical Safe Operating Area Protection. Figure 4. Quiescent Current vs. Supply Voltage. Variable Voltage Power Supply Using The LM317T Variable Voltage Power Supply. The LM317T is a fully adjustable 3 terminal positive voltage regulator capable of supplying 1.5 amps with an output voltage ranging from around 1.25 volts to just over 30 volts. Voltage regulator A simple voltage current regulator can be made from a resistor in series with a diode (or series of diodes). Due to the logarithmic shape of diode V I curves, the voltage across the diode changes only slightly due to changes in current drawn or changes in the input.
