onsemi Adjustable Linear Voltage Regulator 1.25-37 V 1.5 A 40 V SOIC 8-Pin LM317LDR2G

onsemi LM317LDR2G is an adjustable linear voltage regulator designed for industrial and electronic applications requiring precise voltage regulation from 1.25 V to 37 V with an output current capacity up to 1.5 A. This device, housed in a surface mount SOIC 8-pin package, ensures compactness and ease of integration into various PCB designs.

The regulator supports a wide input voltage range from 4.2 V up to 40 V and operates with a very low quiescent current of 3.5 mA, making it energy efficient. It is compliant with the AEC-Q100 automotive standard and can reliably operate in environments with temperatures up to 125°C, suitable for automotive and industrial-grade electronics.

Safety features include short-circuit current limiting, thermal shutdown, and safe-area compensation, protecting the circuit from damage due to overheating or overload conditions. It can be used effectively for on-card voltage regulation, programmable output voltage settings, or as a precision current regulator by connecting a fixed resistor between the adjustment and output pins.

The compact dimensions of 5 mm length, 4 mm width, and 1.5 mm height make it ideal for space-constrained applications. The device is a positive polarity regulator with 8 pins, allowing easy surface mount assembly.

This linear Voltage Regulator offers adjustable output voltage from 1.25 to 37 V. Maximum output current rating is 1.5 A for robust power delivery. Equipped with thermal and current limiting protection to enhance safety and performance.

Compact SOIC 8-pin surface mount package supports high-density PCB designs. Meets AEC-Q100 automotive qualification standards. Designed for applications including power management ICs in industrial, automotive, and laboratory environments.
