The LM317MKVURG3 is a robust adjustable linear regulator from Texas Instruments, capable of sourcing 500mA. Output voltage is set between 1.25V and 37V with two resistors. Housed in a TO-252-3 package, it offers improved heat dissipation for demanding applications. Its high PSRR ensures clean power for analog and digital circuits alike.
- Thermally Efficient DPAK: The TO-252-3 package handles higher power dissipation, enabling reliable operation at higher input-output differentials.
- Adjustable Output: 1.25V to 37V range covers most logic and analog requirements.
- High Ripple Rejection: 80dB~65dB PSRR at 120Hz reduces mains noise in sensitive equipment.
- Proven Reliability: TI's LM317 family is a trusted industry standard with decades of field use.
Power Supply for Automotive ECUs
The TO-252-3 package offers better thermal performance, making it suitable for under-hood electronics that require a stable 5V or 3.3V rail from a 12V battery.
Adjustable Reference for Test Equipment
Use it as a precision adjustable reference in calibration tools, leveraging its 500mA output and wide range for various test voltages.
LED Driver with Current Limiting
Configure as a constant current source for high-brightness LEDs, using the adjustable output to set the desired forward current.
Industrial Control Loops
Provide a clean, adjustable supply for PLC analog outputs, where ripple rejection (80dB) prevents noise from corrupting control signals.
Battery-Powered Devices
Regulate battery voltage down to a stable level for portable instruments, with the 10mA quiescent current being acceptable for moderate power budgets.
Prototyping and Education
Its classic architecture and through-hole compatible DPAK make it ideal for breadboard power supplies in university labs.
