LM317BD2TR4 Description

Short technical summary and product information.

The ON Semiconductor LM317BD2TR4 is a versatile adjustable positive voltage regulator designed for a wide range of applications. It can supply currents 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. It features internal current limiting, thermal shutdown, and safe area compensation, making it highly reliable and essentially blow-out proof. The device is available in a surface-mount D2PAK-3 package.

 

Key electrical specifications include an adjustable output voltage from 1.2V to 37V and an output current capability exceeding 1.5A. It also provides features like internal thermal overload protection and internal short circuit current limiting that remains constant with temperature. The PSRR is rated between 80dB and 65dB at 120Hz.

 

Designed for surface mounting, the LM317BD2TR4 is suitable for local on-card regulation and can be used to create programmable output regulators or precision current regulators by connecting a fixed resistor between the adjustment and output pins.
