Overview
The LM217D2T is a monolithic positive adjustable voltage regulator manufactured by STMicroelectronics in the D2PAK surface-mount package. It delivers an output current exceeding 1.5A with an adjustable voltage range from 1.2V to 37V. The device features 0.1% line and load regulation, floating operation for high voltages, and comprehensive protection including current limiting, thermal shutdown, and safe operating area (SOA) control. Operating junction temperature ranges from -25°C to 150°C.
Feature Summary
- Provides positive adjustable voltage regulation across a wide range using only a resistive divider network.
- Delivers sustained load currents exceeding 1.5A with minimal line and load regulation error.
- Incorporates complete internal protection mechanisms against overcurrent, thermal overload, and safe operating area violations.
Applications
- High-voltage floating power supply designs
- Programmable precision current regulators
- Local on-card voltage regulation
Procurement Notes
Verify the specific ordering suffix matches the required tape-and-reel packaging configuration. Confirm that the component meets RoHS3 compliance standards and check for any recent Product Change Notifications regarding lead modification or inner box changes before finalizing procurement orders.
Selection Notes
Select this component when a robust linear regulator capable of handling high differential input-to-output voltages is required. Ensure the application maintains the junction temperature within the specified -25°C to 150°C range and accounts for the thermal resistance characteristics inherent to the D2PAK package during design.
Part Context
This part belongs to the LM217 family of monolithic integrated circuits designed as positive adjustable voltage regulators. It shares core electrical specifications with the LM117 and LM317 variants but is distinguished by its specific commercial temperature rating and availability in the D2PAK surface-mount form factor.
Replacement Considerations
LM317D2T
FAQ
How is the nominal output voltage determined?
The nominal output voltage is selected by means of a single external resistive divider connected between the output and adjustment terminals.
What protections are included in the device?
The device includes a complete series of protections: current limiting, thermal shutdown, and safe operating area (SOA) control.
