About LM317T

The LM317T is a highly versatile and useful device for electrical engineers, capable of supplying various DC voltage outputs as well as variable voltage outputs up to a maximum of 37V with currents of about 1.5 amperes. Unlike many fixed regulators, the LM317T uses only a resistive divider to select the nominal output voltage, making it an exceptionally easy-to-use device.

When using the minimum version of the LM317T circuit, only two resistors are required, along with input and output capacitors, to determine the output voltage. The reference voltage provided by the device varies between 1.2 and 1.3V, with an average of 1.25V, which is maintained at resistor R1. By adjusting resistor R2, the output voltage can be increased, as the voltage drop across R2 is added to the 1.25V at R1 to create the overall output voltage.

Overall, the LM317T provides electrical engineers with a simple, yet powerful tool for creating various DC voltage outputs, with the convenience and flexibility of a variable output voltage with a maximum of 37V. Its ease of use and versatility make it an essential element in any engineer’s toolkit.
