LM217T-DG

Overview

The LM217T-DG is a positive adjustable linear voltage regulator manufactured by STMicroelectronics. It provides an output current exceeding 1.5 A with an adjustable voltage range from 1.2 V to 37 V. The device features line regulation of 0.02 %/V and load regulation of 0.3 %. It operates within a temperature range of -25 °C to +150 °C and supports a maximum input voltage of 40 V. The component utilizes a TO-220-3 through-hole package.

Feature Summary

Provides internal complete series protections including current limiting, thermal shutdown, and safe operating area (SOA) control.
Supports floating operation for high voltage applications.
Enables easy design implementation via resistive divider selection for nominal output voltage.

Applications

Positive adjustable voltage regulators
Local on-card regulation
Battery chargers

Procurement Notes

Verify the specific suffix 'DG' against the official STMicroelectronics datasheet to confirm pinout and packaging details. Ensure the ordering information matches the required TO-220-3 form factor. Confirm RoHS compliance status directly from the manufacturer's documentation before procurement.

Selection Notes

Select this component when a robust positive adjustable regulator is required for currents above 1.5 A. The wide operating temperature range suits industrial environments. Verify that the input voltage does not exceed the 40 V maximum limit during system design.

Part Context

This part belongs to the LM217/LM317 family of monolithic integrated circuits designed as positive adjustable voltage regulators. The LM217 variant typically offers extended temperature performance compared to standard commercial grades. It shares functional similarities with other adjustable regulators but is distinguished by its specific electrical ratings and protection features.
