LM317MDCY Description

Short technical summary and product information.

The LM317MDCY from Texas Instruments is a versatile adjustable 3-terminal positive voltage regulator. It is designed to supply over 500mA with an output voltage range adjustable from 1.25V to 37V. This regulator is easy to use, requiring only two external resistors to set the output voltage.

 

Key features include internal short-circuit current limiting, thermal-overload protection, and output safe-area compensation, ensuring reliable operation under various conditions. The device operates over a temperature range of -40°C to 125°C (TJ).

 

Packaged in a surface-mount SOT-223-4 (TO-261-4, TO-261AA) case, the LM317MDCY is suitable for a wide array of applications. Its adjustable nature and robust protection features make it a good choice for power supply designs where flexibility is required.

 

Applications include electronic point-of-sales systems, medical and health devices, printers, appliances, and set-top boxes. The regulator's floating design allows for high output voltages when needed, provided the input-to-output differential does not exceed 40V.
