LM217MT

Overview

The LM217MT is a medium current positive adjustable voltage regulator manufactured by STMicroelectronics. It provides an output voltage range from 1.2 V to 37 V with a maximum load current of 500 mA. The device features line regulation of 0.01% and load regulation of 0.1%. It includes thermal overload protection, short-circuit protection, and output safe area compensation. Operating junction temperature ranges from -40°C to 125°C. Input-output differential voltage is rated at 40 V. The component is housed in a DPAK surface-mount package.

Feature Summary

Monolithic integrated circuit designed for positive adjustable voltage regulation
Includes internal thermal overload protection and short-circuit protection
Features output transition safe area compensation for high voltage applications
Nominal output voltage selected via external resistive divider

Applications

General purpose power supplies
Local on-card regulation
Programmable output regulators
Precision current regulators

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm the exact package type and reel specifications. Ensure that the procurement channel sources components directly from authorized distributors or verified suppliers to guarantee authenticity. Confirm RoHS compliance status and environmental certifications prior to finalizing orders.

Selection Notes

Select this component when a medium current adjustable regulator is required for designs needing up to 500 mA. Consider the DPAK package for surface-mount assembly requirements. Evaluate thermal resistance characteristics relative to the expected power dissipation and ambient operating conditions. Verify input-to-output voltage differentials remain within the specified absolute maximum ratings.

Part Context

This part belongs to the LM217M series of monolithic integrated circuits intended for use as positive adjustable voltage regulators. It shares functional similarities with the LM317M but is distinguished by its extended operating temperature range starting at -40°C. The series is designed to eliminate the need for stocking multiple fixed regulators by allowing flexible voltage configuration.
