Overview
The LM117GW-QML is a military-grade, three-terminal adjustable positive voltage regulator manufactured by Texas Instruments. It provides an output voltage range from 1.2 V to 37 V, set via two external resistors. The device supports a maximum load current of 1.5 A and operates with a maximum input voltage of 40 V. It features internal current limiting, thermal overload protection, and safe operating area protection. The component is qualified under the QML (Military) standard and is housed in a ceramic SOIC-16 package.
Feature Summary
- Military qualification compliant with QML standards for high-reliability applications
- Integrated thermal overload and current limit protection mechanisms
- Adjustable output voltage capability using external resistor networks
Applications
- Military avionics power systems
- Spacecraft electronic subsystems
- High-reliability industrial control equipment
Procurement Notes
Verify that the specific part number suffix matches the required military qualification level. Confirm package integrity and lead time requirements with authorized distributors. Ensure compliance with all relevant defense procurement specifications before finalizing orders.
Selection Notes
Select this component when military reliability standards are mandatory. It is suitable for designs requiring robust overcurrent and thermal protection in harsh environments. Consider the ceramic package for superior environmental resistance compared to plastic variants.
Part Context
This regulator belongs to the LM117 family of three-terminal adjustable positive regulators. The QML designation indicates it meets rigorous military quality and reliability standards, distinguishing it from commercial or automotive grades within the same functional family.
