The LM317LCLP from Texas Instruments is a classic adjustable linear regulator in a TO-92 package. It outputs a stable voltage from 1.2V to 32V, delivering up to 100mA. With a quiescent current of 2.5 mA and 80dB PSRR at 120Hz, it is ideal for low-power audio, instrumentation, and reference circuits. Its through-hole TO-92 form factor is perfect for breadboarding and compact PCB layouts.
- Versatile Adjustability: Output from 1.2V to 32V with just two external resistors.
- Proven Reliability: Industry-standard LM317 architecture with decades of field use.
- Low Noise Operation: 80dB PSRR at 120Hz ensures clean DC for sensitive analog circuits.
- Compact TO-92: Ideal for space-constrained, low-current applications.
Adjustable Bench Power Supplies
The 1.2V to 32V adjustable range makes it perfect for hobbyist and lab power supplies, providing a stable 100mA for logic circuits.
LED Driver for Indicators
Set the output to 3.3V or 5V to drive indicator LEDs with constant current via a series resistor, using the TO-92 package for compact designs.
Bias Supply for Op-Amps
Provides a clean, adjustable positive rail for single-supply op-amp circuits, with 80dB PSRR at 120Hz rejecting mains hum.
Reference Voltage Source
Use as a precision adjustable reference for ADC calibration, leveraging its 2.5 mA quiescent current for stable operation.
Battery Charger for NiMH Cells
Configure the output to 1.4V per cell for trickle charging small NiMH batteries, with current limited by the 100mA max.
Audio Preamplifier Supply
Its low noise and adjustable output make it suitable for biasing JFET input stages in guitar pedals and microphones.
