LM217MDT-TR

Overview

The LM217MDT-TR is a monolithic positive adjustable voltage regulator in the DPAK surface-mount package. It provides an output voltage range from 1.2 V to 37 V with a maximum load current exceeding 500 mA. The device features thermal overload protection, short-circuit protection, and output safe area compensation. Electrical characteristics include a line regulation of 0.01% typical and load regulation of 0.1% typical at 25 °C. Operating junction temperature ranges from -40 °C to 125 °C.

Feature Summary

Positive adjustable voltage regulation with a wide output range
Integrated thermal overload and short-circuit protection
Output transition safe area compensation for high voltage applications
Floating operation capability for high voltage supplies

Applications

General purpose positive adjustable power supplies
Local on-card regulation for distributed power systems
Programmable output regulators using external resistors
Precision current regulators via fixed resistor connection

Procurement Notes

Verify the component matches the specific STMicroelectronics datasheet DS0522 Rev 13. Confirm the DPAK (TO-252) package type and the TR suffix indicating tape and reel packaging. Ensure the ordering code corresponds exactly to the LM217MDT-TR designation to avoid confusion with other package variants or pinouts.

Selection Notes

Select this component when a medium-current adjustable regulator is required in a compact surface-mount form factor. The DPAK package supports up to 500 mA load current. Consider the thermal resistance values for heat dissipation requirements. Verify that the input-to-output differential voltage does not exceed the absolute maximum rating of 40 V during operation.

Part Context

This part belongs to the LM217M series of medium-current adjustable voltage regulators manufactured by STMicroelectronics. It shares functional similarities with the LM317M but is optimized for commercial temperature ranges. The series is designed to replace multiple fixed regulators by allowing voltage adjustment through a single external resistor divider network.
