The LM317LCLPR is a reliable adjustable linear regulator from Texas Instruments. It delivers up to 100mA with an output voltage adjustable from 1.2V to 32V. Its low quiescent current and high PSRR make it suitable for noise-sensitive and battery-powered circuits. The TO-92-3 package is ideal for compact, through-hole designs.
- Versatile Adjustable Output: Set any voltage from 1.2V to 32V with two resistors, simplifying design.
- Low Power Consumption: 2.5 mA quiescent current extends battery life in portable devices.
- Excellent Ripple Rejection: 80dB PSRR at 120Hz ensures stable output for analog circuits.
- Robust TO-92 Package: Easy to handle and solder in through-hole PCBs.
Portable Instrumentation
The low 2.5 mA quiescent current and adjustable output make it perfect for battery-operated meters and handheld test equipment.
Sensor Conditioning
Provide a clean, adjustable supply for bridge sensors and signal conditioning op-amps, leveraging the high PSRR to reduce noise.
Communication Interfaces
Power RS-232 transceivers or CAN transceivers with a stable, adjustable voltage derived from a higher system rail.
Automotive Electronics (Non-Q1)
For non-automotive-grade applications, it can regulate power for infotainment or body control modules in lab or aftermarket setups.
Variable Bench Supplies
