The LM317HVH/NOPB is a high-voltage adjustable linear regulator from Texas Instruments, capable of delivering 1.5A with an output range from 1.25V to 57V. Housed in a rugged TO-3 package, it offers excellent line and load regulation. With a low quiescent current of 12mA and high PSRR, it ensures clean power for sensitive applications. Its robust design includes internal current limiting and thermal shutdown, making it a reliable choice for demanding industrial and audio power supplies.
- High Output Voltage Capability: Supports up to 57V output, enabling use in high-voltage industrial and telecom systems where standard LDOs fail.
- High Output Current: 1.5A capability powers multiple circuits or heavier loads without needing external pass transistors.
- Excellent Ripple Rejection: 80dB PSRR at 120Hz minimizes mains hum, critical for high-fidelity audio and precision measurement.
- Robust TO-3 Package: Metal can package provides superior thermal dissipation for reliable operation at high current and voltage.
High-Voltage Industrial Power Supplies
With an output voltage capability up to 57V, the LM317HVH/NOPB is ideal for industrial control systems requiring a stable, adjustable high-voltage rail from a 60V input source.
Bench Power Supply Projects
Hobbyists and labs can build a versatile 1.25V to 57V bench supply. The 1.5A current capability supports a wide range of analog circuits and small motors.
Telecom Line Drivers
Telecom equipment often needs higher voltage rails (e.g., 48V). This regulator provides a clean, low-noise 48V output from a 50-60V input, ensuring reliable line driver performance.
Audio Amplifier Front-Ends
The high PSRR (80dB at 120Hz) makes it suitable for powering sensitive analog audio stages, reducing hum and ripple from unregulated supplies.
HV Test Equipment
For calibration and test fixtures requiring adjustable high DC voltages, the LM317HVH/NOPB offers a simple, robust solution with thermal overload protection.
Automotive Aftermarket Electronics
In 24V automotive systems, this regulator can step down to a stable 12V or 5V rail for aftermarket sensors and controllers, handling load transients up to 1.5A.
