LM317BD2TR4G Description

Short technical summary and product information.

The LM317BD2TR4G from ON Semiconductor is a versatile adjustable positive linear voltage regulator. It is designed to supply in excess of 1.5A over an output voltage range of 1.2V to 37V. This regulator is easy to use, requiring only two external resistors to set the output voltage.

 

Key electrical specifications include a maximum input voltage of 40V and a maximum output current of 1.5A. It features internal current limiting, thermal shutdown, and safe area compensation, making it robust for various applications. The device operates within a temperature range of -40°C to 125°C.

 

Packaged in a surface-mount D2PAK-3 (TO-263-3) package, the LM317BD2TR4G is suitable for applications requiring space-saving solutions. Its adjustable nature eliminates the need to stock many fixed voltage regulators, making it a flexible choice for prototyping and production.

 

This regulator is also Pb-Free, Halogen Free/BFR Free, and RoHS Compliant. It is well-suited for local, on-card regulation, programmable output regulators, and precision current regulation.
