The LM317T is a popular variable voltage regulator that is used in power regulation circuits by hobbyists and professionals alike. The output voltage of LM317 can be adjusted from 1.2V to 37V with a maximum output current rating of 1.5A. The IC is commonly used for voltage regulation and current regulation circuits in chargers and other power modules. It comes in a breadboard friendly TO220 package and required very simple external components, few resistors, and a capacitor to operate as a function circuit. It can be used in positive voltage regulator circuits, Variable Power Circuits like battery chargers, and are commonly used in Desktop PC, DVDs, and other consumer products.
- Output Voltage: 1.25V to 37V
- Output Current: 1.5A (Max)
- Recommended difference between input and output voltage: 15V
- TO-220 Package
This is a 3-legged device with pins named Adjust Pin, Input Voltage Pin, and Output Voltage Pin. To use LM317T, you have to supply the input voltage to an input pin, and using a potential divider circuit, you have to provide the voltage to adjust the voltage pin to regulate the voltage at the output pin.
