The LM317HVT/NOPB is a high-voltage adjustable LDO regulator from Texas Instruments, offering output from 1.25V to 57V and up to 1.5A. With excellent PSRR and robust TO-220 packaging, it is a versatile choice for power supplies, chargers, and audio applications requiring high input voltage capability.
- Adjustable output (1.25V-57V): Flexible for a wide range of applications.
- High output current (1.5A): Drives substantial loads.
- High PSRR (80dB@120Hz): Excellent ripple rejection for clean DC rails.
- High input voltage capability: Handles up to 60V inputs safely.
High-Voltage Power Supplies
Adjustable output up to 57V makes it suitable for bench power supplies, tube amplifiers, and industrial equipment.
Battery Chargers
Constant voltage/current capability (with external resistors) enables simple lead-acid or lithium battery chargers.
Audio Amplifier Biasing
Low noise and high PSRR (80dB at 120Hz) provide clean rails for preamplifiers and audio circuits.
Laboratory Test Equipment
Adjustable output and 1.5A current drive support prototyping, breadboarding, and general lab use.
HV DC-DC Post-Regulation
Cleans up ripple from switching converters in high-voltage applications.
Industrial Control Systems
Robust TO-220 package and wide voltage range suit PLCs, motor drives, and process controllers.
