The LM117K STEEL from Texas Instruments is a robust adjustable linear regulator capable of delivering 1.5A across an output range of 1.25V to 37V. Its high PSRR (80dB at 120Hz) and 5 mA quiescent current make it a reliable choice for audio, industrial, and test equipment. The TO-3-2 metal package ensures excellent thermal performance for demanding applications.
- Wide Adjustable Range: Output from 1.25V to 37V provides design flexibility for various voltage requirements.
- High Current Capacity: 1.5A output supports power-hungry loads.
- Excellent Ripple Rejection: 80dB PSRR at 120Hz ensures clean DC output from rectified AC sources.
- Durable Package: TO-3 metal can offers superior heat dissipation and mechanical robustness.
Adjustable Bench Power Supplies
The 1.25V to 37V adjustable range and 1.5A current capability make it ideal for hobbyist and lab bench power supplies requiring a flexible output.
High-Power Audio Amplifiers
With 80dB PSRR at 120Hz, it effectively filters mains ripple, providing clean DC rails for audio preamplifiers and low-power amplifier stages.
Industrial Control Systems
The robust TO-3 metal package handles higher thermal loads, making it suitable for industrial controllers operating in harsh environments.
Battery Chargers
Its adjustable output allows precise voltage settings for charging lead-acid or lithium battery packs up to 37V.
Test & Measurement Equipment
The low noise and high PSRR characteristics ensure stable reference voltages for precision measurement instruments.
HV Power Supplies for Tubes
Can be used to generate stable bias voltages for vacuum tube circuits, where higher voltages are required.
