LM317BT Description

Short technical summary and product information.

The ON Semiconductor LM317BT is a versatile adjustable positive voltage regulator designed for a wide range of applications. It can supply an output current in excess of 1.5A, with an adjustable output voltage ranging from 1.2V to 37V. This regulator is easy to use, requiring only two external resistors to set the output voltage.

 

Key features include internal current limiting, thermal shutdown, and safe area compensation, making it highly reliable and essentially blow-out proof. The device operates over a temperature range of -40°C to 125°C. Its TO-220 package with through-hole mounting makes it suitable for various circuit designs.

 

The LM317BT is ideal for local, on-card regulation and can also be configured as a programmable output regulator or a precision current regulator by adding a fixed resistor. Its robust design ensures stability and protection against common electrical faults.
