LM140K-5.0/NOPB

Overview

The LM140K-5.0/NOPB is a three-terminal positive linear voltage regulator from Texas Instruments, delivering a fixed 5 V output with a maximum current of 1 A. It operates within an input voltage range of 7.5 V to 35 V and features a typical power supply rejection ratio of 72 dB. The device supports through-hole mounting in a TO-3-2 package, ensuring robust performance across an extended temperature range from -55 °C to +125 °C.

Feature Summary

Provides stable fixed 5 V regulation for industrial applications
Supports high load currents up to 1 A
Ensures reliable operation in extreme environmental conditions

Applications

Industrial control systems requiring regulated power supplies
Embedded systems needing stable 5 V logic levels
Power management circuits in harsh environments

Procurement Notes

Verify the exact part number against official Texas Instruments documentation to confirm specifications. Ensure compatibility with your thermal management design, as the TO-3-2 package requires adequate heat dissipation. Check for any specific handling requirements related to the through-hole installation process.

Selection Notes

Select this component when a fixed 5 V output with 1 A capability is required in a rugged environment. Consider the TO-3-2 package for its durability and ease of mounting on heatsinks. Evaluate the input voltage range to ensure it meets your system's power supply variations.

Part Context

This regulator belongs to the LM140K series, designed for industrial-grade performance. It offers a fixed output voltage option among other variants. The series is known for its reliability and ability to handle significant load currents while maintaining regulation under varying line and load conditions.
