Overview
The LM117HVH is a high-voltage three-terminal adjustable positive linear voltage regulator manufactured by Texas Instruments. It provides an output current capability of 1.5 A with an adjustable output voltage range extending up to 60 V. The device operates within a junction temperature range of -55 °C to +125 °C and features a typical line regulation of 0.04 %/V and load regulation of 0.5 %. It includes comprehensive protection mechanisms such as internal current limiting, thermal overload protection, and safe operating area control.
Feature Summary
- High-voltage operation supporting input voltages up to 60 V
- Integrated circuit limiting and thermal shutdown for robust reliability
- Adjustable output voltage configuration using external resistors
Applications
- High-voltage power supply systems
- Industrial equipment requiring adjustable positive regulation
- Military and aerospace electronic circuits
Procurement Notes
Verify the specific datasheet version and manufacturer documentation to confirm exact electrical parameters and pinout configurations. Ensure that the TO-39 package style matches the intended mechanical design constraints. Cross-reference the part number against official Texas Instruments catalogs to validate availability and compliance status before finalizing procurement plans.
Selection Notes
Select this component when applications require a robust adjustable regulator capable of handling high input voltages up to 60 V. The LM117HVH is suitable for designs needing 1.5 A output current with integrated thermal and current protection. Consider the through-hole TO-39 package requirements and the wide operating temperature range for harsh environment deployments.
Part Context
This device belongs to the LM117 family of three-terminal adjustable positive regulators. It shares functional similarities with standard LM117 variants but is specifically engineered for high-voltage applications. The HV designation indicates enhanced breakdown voltage capabilities compared to lower-voltage counterparts in the same product series.
