ON Semiconductor LM317MDTRKG Adjustable Voltage Regulator, 1.2V to 37V, 500mA,

The LM317MDTRKG is a versatile adjustable positive voltage regulator from ON Semiconductor, delivering over 500mA output current with an adjustable output range of 1.2V to 37V. This regulator simplifies design by requiring only two external resistors to set the desired output voltage, making it an ideal choice for a wide range of electronic applications.

Featuring internal current limiting, thermal shutdown, and safe area compensation, this device provides robust protection against overloads and short circuits, ensuring reliable operation in demanding conditions. Its floating operation enables use in high-voltage applications, while the 4% output voltage tolerance ensures consistent performance.

The regulator supports an input voltage up to 40V and operates over a temperature range of 0°C to 125°C. Its surface-mount TO-252-3 package (with 3 pins) allows for compact PCB integration, suitable for on-card regulation and other space-constrained designs.

This component is particularly suited for automotive, power management, and industrial systems, where stable and adjustable power supplies are critical. It eliminates the need to stock multiple fixed-voltage regulators, offering flexibility and cost efficiency in production.
