What is adjustable voltage regulator?
An adjustable voltage regulator produces a DC output voltage, which can be adjusted to any other value of certain voltage range. Hence, adjustable voltage regulator is also called as a variable voltage regulator. The DC output voltage value of an adjustable voltage regulator can be either positive or negative.
What is the current rating of voltage regulator IC lm338k?
Here is the LM338 Adjustable DC power supply circuit, 1.2V to 30V. It can provide a current maximum to 5A and 10A.
What is the difference between fixed voltage regulator and adjustable regulator?
Adjustable Voltage regulators require a very few external components to achieve its operation. Fixed voltage regulators require almost no external components (may be a couple of bypass capacitors). At low cost you have a wide range of voltage and current selection.
What is LM317 3-terminal adjustable voltage regulator?
In Depth Guide: LM317 3-Terminal Adjustable voltage Regulator LM317 is a positive-voltage regulator with an adjustable voltage range from 1.25 V to 37 V. It can supply greater than 1.5 A at the output. In most of the applications, due to irregular loads, the output voltage produced has fluctuations in it which can lead to damaging loads.
What is the program resistor for the LM317?
The input voltage to the LM317 must be at least 1.5v greater than the output voltage. This calculator will work for most DC Voltage Regulators with a reference voltage (VREF) of 1.25. Typically, the program resistor (R1) is 240 ohms for the LM117, LM317, LM138, and LM150.
What is the voltage output of the LM317 power supply?
For example LM317 circuit Variable DC Power Supply 1.2V to 30V 1AFirst projects Linear power supply Regulator selector 1.5V,3V,4.5V,5V,6V,9V at 1.5A It’s easy to selects voltage output. 0-60 volt 30V Dual DC variable power supply using LM317 LM337 It’s high volt and start voltage at zero! good job.
What are the details of pins of an adjustable voltage regulator?
The details of pins are as under: Pin1 is an adjustable pin which is used to adjust the output voltage. Pin2 is an output pin and gives a regulated voltage. An unregulated input voltage is applied at pin 3. This picture shows a functional block diagram of the adjustable voltage regulator.
