The LM317G from EVVO is a versatile adjustable linear regulator with an output range of 1.2V to 37V and a current capability of 1.5A. Its low quiescent current of 12mA and high PSRR make it suitable for audio, battery charging, and general-purpose power supplies. The SOT-223-3L package offers a compact footprint.
- Adjustable Output: 1.2V to 37V provides maximum flexibility.
- High Current: 1.5A supports a wide range of loads.
- Excellent PSRR: 75dB at 120Hz ensures clean output.
- Robust Protection: Internal current limiting and thermal shutdown.
Variable Bench Power Supplies
The LM317G's adjustable output from 1.2V to 37V makes it ideal for hobbyist and lab power supplies. Its 1.5A current capability handles most prototyping needs.
Battery Chargers
With external resistors, it can be configured as a constant-voltage charger for lead-acid or Li-ion batteries, providing a stable charging voltage.
Audio Amplifier Supplies
Its high PSRR (75dB at 120Hz) ensures clean DC rails for audio amplifiers, reducing hum and noise.
LED Drivers
By setting the output voltage, the LM317G can drive high-power LEDs with constant voltage, simplifying current limiting with a series resistor.
Solar Panel Regulators
In off-grid systems, it regulates the output from solar panels to charge batteries or power loads directly.
Test Equipment
Its adjustable nature makes it a staple in benchtop instruments where a precise, variable voltage is required.
