Description
The LM317 Series are 3-terminal positive adjustable voltage regulators which offer improved performance over earlier devices. A major feature of the LT117A is the output voltage tolerance is guaranteed at a maximum of +1%, allowing an overall power supply tolerance to be better than 3% using inexpensive 1% resistors. Line and load regulation performance has been improved as well.
Applications
1. Wide range power supplies
2. Constant Current Supplies
3. Voltage Programmable Supplies
Overall, the LM317 is a versatile and reliable component that is widely used in electronic circuits to provide regulated voltage outputs. Its adjustable output voltage feature, combined with its ease of use and availability, has made it a popular choice for designers and hobbyists alike.
