LM1117ILD-5.0/NOPB

Overview

The LM1117ILD-5.0/NOPB is a fixed-output low-dropout linear regulator manufactured by Texas Instruments, providing a stable 5 V output with a maximum load current of 800 mA. It operates within an extended industrial temperature range of -40°C to +125°C and utilizes a TO-252 (DPAK) surface-mount package. The device features a typical dropout voltage of 1.2 V at full load, ensuring efficient power conversion. Internal circuitry includes Zener-trimmed bandgap references for ±1% output accuracy, alongside built-in current limiting and thermal shutdown protection mechanisms.

Feature Summary

Industrial-grade operational capability across the -40°C to +125°C temperature spectrum
Integrated current limiting and thermal shutdown for enhanced system reliability
Low dropout performance enabling efficient regulation from higher input voltages
Fixed 5 V output with high line and load regulation specifications

Applications

Post-regulator stages for switching DC-DC converters
Battery charger circuits requiring precise voltage control
Portable instrumentation power supplies
Active SCSI termination regulators

Procurement Notes

Verify that the specific suffix 'ILD' corresponds to the intended TO-252 package variant and industrial temperature grade as documented in official datasheets. Confirm the presence of the '/NOPB' designation indicates lead-free and RoHS compliance status. Ensure ordering documentation matches the exact part number to avoid confusion with similar family members or alternative package options.

Selection Notes

Select this component when a fixed 5 V rail is required under industrial environmental conditions. The TO-252 package offers a balance between thermal dissipation capabilities and space efficiency for surface-mount designs. Consider the 800 mA current limit and dropout characteristics relative to the specific input voltage and load profile to ensure stable operation without excessive heat generation.

Part Context

This device belongs to the LM1117 series of low-dropout linear regulators produced by Texas Instruments. The series provides both adjustable and fixed voltage options in various packages including SOT-223, TO-220, and WSON. The LM1117 is widely recognized for its compatibility with standard three-terminal regulator footprints while offering superior dropout performance compared to older legacy technologies.
