Overview
The LM117K STEEL is an extended temperature, adjustable linear voltage regulator manufactured by Texas Instruments. It provides a positive output current of 1.5 A with an adjustable output voltage range from 1.2 V to 32 V. The device operates within a junction temperature range of -55 °C to +150 °C and features internal short-circuit protection. It is housed in a TO-3-2 (TO-CAN) package designed for through-hole mounting.
Feature Summary
- Extended temperature operation capability for harsh environments
- Internal short-circuit protection for enhanced reliability
- Adjustable output voltage regulation
Applications
- Industrial power supplies requiring wide temperature tolerance
- Military and aerospace electronic systems
- High-reliability adjustable voltage regulation circuits
Procurement Notes
Verify the specific suffix against official Texas Instruments documentation to confirm exact electrical characteristics and packaging details. Ensure compatibility with high-temperature operational requirements before integration into final designs.
Selection Notes
Select this component when fixed-output regulators are insufficient and wide thermal stability is required. Consider the TO-3-2 package size and thermal dissipation capabilities relative to the application's heat management constraints.
Part Context
This part belongs to the LM117 series of adjustable linear regulators. It shares functional similarities with other LM117 variants but is distinguished by its extended temperature rating and steel-can packaging, targeting ruggedized applications.
Replacement Considerations
Consult official substitution guides for equivalents such as LM117KSTEEL/NOPB or compatible industrial-grade adjustable regulators from other manufacturers ensuring identical pinout and thermal specifications.
