LM117HVK-QML

Overview

The LM117HVK-QML is a space-grade, three-terminal adjustable positive linear regulator manufactured by Texas Instruments. It supports an input voltage range up to 60V and delivers a maximum output current of 1.5A. The device features an adjustable output voltage range from 1.2V to 57V, set via two external resistors. It operates within a temperature range of -55°C to 150°C and utilizes a TO-3 metal can package. Integrated protections include internal current limiting, thermal overload shutdown, and safe operating area protection.

Feature Summary

Space-grade qualification for high-reliability applications
Integrated thermal overload and current limit protection
Adjustable output voltage via external resistors
Robust metal can packaging for harsh environments

Applications

Satellite power distribution systems
Spacecraft subsystem regulation
High-reliability industrial power supplies
Avionics voltage regulation

Procurement Notes

Verify the specific QML qualification level and lot traceability documentation upon order confirmation. Ensure that the procurement channel provides valid certification for space-grade components. Confirm the package variant matches the required mechanical interface. Request full test data sheets if specified for mission-critical deployment.

Selection Notes

Select this component when high input voltage tolerance and ruggedness are required. It serves as a direct upgrade to standard commercial grade regulators in aerospace contexts. Consider the TO-3 package size for thermal management requirements. Verify that the 1.5A current rating meets the load demands without exceeding safe operating limits.

Part Context

This part belongs to the LM117 family of adjustable linear regulators. It shares functional similarities with the LM317 but offers enhanced durability and higher voltage ratings suitable for demanding environments. The QML suffix indicates qualification under military or space standards, distinguishing it from commercial variants like the LM117HV.
