LM317T Description

Short technical summary and product information.

The LM317T is a versatile adjustable positive voltage regulator designed to supply over 1.5A of load current. Its output voltage can be adjusted from 1.2V to 37V using a simple resistive divider, eliminating the need to stock multiple fixed regulators. This component is suitable for various applications including constant voltage or current regulation, battery charging, and AC voltage regulation.

 

Key electrical specifications include a maximum input voltage of 40V and a minimum input voltage of 4.2V. It provides good line and load regulation, with typical ripple rejection of 80dB. The device operates within a temperature range of 0°C to 125°C.

 

The LM317T is available in a Through Hole package, specifically the TO-220-3 configuration. This mounting style is common for power applications requiring heat dissipation. The component dimensions are 9.15mm in height, 10.4mm in length, and 4.6mm in width.
