LD1117DT28TR

Overview

The LD1117DT28TR is a positive fixed linear voltage regulator manufactured by STMicroelectronics, delivering a precise output of 2.85V with a maximum continuous current capability of 800mA. Designed for low dropout applications, it maintains regulation with an input voltage range up to 15V and exhibits a maximum voltage drop of 1.2V at full load. The device incorporates internal thermal overload and short-circuit current limiting protections to ensure operational reliability under fault conditions. It operates within an industrial temperature range of 0°C to 125°C and utilizes the DPAK (TO-252) surface-mount package for efficient thermal dissipation.

Feature Summary

Provides stable 2.85V fixed output with high accuracy
Delivers up to 800mA output current capability
Integrates over-current and thermal shutdown protection mechanisms

Applications

Battery-powered equipment requiring regulated power rails
Portable consumer electronics systems
General-purpose linear power supply circuits

Procurement Notes

Verify component authenticity through authorized distribution channels due to potential counterfeit risks. Confirm RoHS compliance status as specific listings indicate non-compliance. Validate package integrity upon receipt to ensure solderability. Check manufacturing date codes against project lifecycle requirements. Ensure storage conditions prevent moisture damage prior to reflow soldering processes.

Selection Notes

Select this component when a fixed 2.85V rail is required with moderate current demands. Consider the DPAK package for its balance of thermal performance and board space efficiency. Evaluate input-output differential voltage to ensure operation remains within the specified dropout limits. Verify that the 800mA current rating suffices for peak load conditions without exceeding thermal constraints.

Part Context

This part belongs to the LD1117 series of low-dropout positive voltage regulators from STMicroelectronics. The series offers various fixed output voltages and adjustable versions in multiple packages including SOT-223, TO-220, and SO-8. The DT suffix denotes the DPAK surface-mount packaging variant, optimized for automated assembly and improved thermal characteristics compared to through-hole alternatives.
