The LM317MABDTRKG from onsemi is a versatile adjustable linear regulator capable of delivering 500mA with an output range from 1.2V to 37V. This makes it a flexible solution for a wide variety of applications, from simple fixed-voltage supplies to adjustable bench power sources. With a quiescent current of 10 mA and high PSRR, it provides stable and clean power. The DPAK package is suitable for surface-mount designs requiring moderate power handling.
- Versatile Adjustability: Output voltage from 1.2V to 37V allows one part to serve multiple design requirements, reducing inventory.
- High Ripple Rejection: 80dB PSRR at 120Hz ensures clean DC output, critical for audio and precision analog circuits.
- Robust Current Capability: 500mA output can drive a wide range of loads, from sensors to small motors.
- Surface-Mount Package: DPAK package supports automated assembly and efficient heat dissipation for PCB designs.
Adjustable Power Supply for Lab Equipment
The 1.2V to 37V adjustable range makes it ideal for benchtop power supplies where a variable output is needed for testing various circuits.
LED Driver with Current Limiting
By configuring the LM317 as a constant current source, it can drive high-brightness LEDs with up to 500mA, ensuring consistent brightness.
Battery Charger for 12V Systems
With a 12V input, the adjustable output can be set to charge 9V or 10.8V battery packs, providing a simple charging solution.
Audio Amplifier Pre-Regulator
Its 80dB PSRR at 120Hz helps reduce hum from rectified AC, making it a good pre-regulator for audio circuits.
Industrial Sensor Interface
For sensors requiring a non-standard voltage (e.g., 5.5V), the adjustable output provides a precise supply, improving measurement accuracy.
Prototyping and Breadboarding
The DPAK package can be mounted on adapters, offering a versatile adjustable regulator for hobbyist and educational projects.
