LM217MS-TR

Overview

The LM217MS-TR is a monolithic positive adjustable voltage regulator from the LM217M series, manufactured by STMicroelectronics. It operates in an SOT223 surface-mount package and provides an output current exceeding 500 mA. The device allows for continuous output voltage adjustment between 1.2 V and 37 V using a single external resistor divider. Key electrical specifications include a typical line regulation of 0.01% and load regulation of 0.1%. The component supports floating operation for high-voltage applications and includes built-in thermal overload and short-circuit protection mechanisms.

Feature Summary

Provides positive adjustable voltage regulation with a wide output range
Includes internal thermal overload and short-circuit protection circuits
Supports floating operation suitable for high-voltage power supply designs

Applications

General-purpose linear power supply regulation
Local on-card voltage regulation for distributed power systems
Precision current regulators when configured with fixed resistors

Procurement Notes

Verify that the specific ordering suffix matches the required SOT223 tape-and-reel packaging configuration. Confirm compliance with environmental directives such as RoHS standards applicable to the manufacturing batch. Ensure the selected variant aligns with the intended operating temperature range requirements for the final assembly process.

Selection Notes

Select this component when a medium-current adjustable regulator is needed in a compact surface-mount form factor. The SOT223 package offers a balance between thermal performance and board space efficiency compared to larger through-hole options. Consider the maximum input-to-output differential voltage limits when designing for high-voltage drop scenarios.

Part Context

This part belongs to the LM217M family of medium-current adjustable voltage regulators. It shares functional similarities with the LM317M but is distinguished by its extended low-temperature operating capability down to -40 °C. The device serves as a versatile alternative to fixed-voltage regulators, reducing inventory complexity by allowing customizable output voltages via external components.
