LM1117GS-5.0

Overview

The LM1117GS-5.0 is a fixed-output positive low-dropout linear voltage regulator manufactured by TAEJIN (HTC Korea). It provides a stable 5.0V output with a maximum continuous current of 1A. The device operates within an input voltage range up to 15V and features a typical dropout voltage of 1.2V at full load. Line regulation is typically 0.1%, and load regulation is typically 0.2%. It includes internal current limiting and thermal shutdown protection, functioning reliably across a junction temperature range of -40°C to +125°C.

Feature Summary

Delivers up to 1A output current with very low dropout voltage characteristics
Includes built-in internal current limit and thermal shutdown protection mechanisms
Offers high line and load regulation performance for stable power delivery
Available in a compact SOT-223-3L surface mount package

Applications

Active SCSI terminators
Portable and notebook computers
SMPS post regulators
Motherboard clock supplies
Battery chargers

Procurement Notes

Verify the manufacturer designation as TAEJIN or HTC Korea when sourcing this component. Confirm the specific suffix indicates the 5.0V fixed version. Ensure the package matches the SOT-223-3L form factor required for your PCB layout. Check for moisture sensitivity level 3 compliance if reflow soldering is part of your assembly process.

Selection Notes

Select this regulator when a 5V rail is required with currents up to 1A. Consider the thermal resistance limits of the SOT-223-3L package under your specific ambient conditions. Ensure the input voltage does not exceed the absolute maximum rating of 20V. Verify that the output capacitor meets the stability requirements specified in the datasheet.

Part Context

This component belongs to the LM1117 series of low-dropout linear regulators. It serves as a positive-voltage regulator designed for battery-powered applications and portable electronics. The series offers both adjustable and fixed output versions, providing flexibility for various power management needs in consumer and industrial devices.
