ON Semiconductor LM317BTG 1.2V to 37V Adjustable Positive Voltage Regulator TO-

The ON Semiconductor LM317BTG is a highly versatile adjustable positive voltage regulator, engineered to deliver robust power management in a wide array of electronic applications. This three-terminal regulator can supply over 1.5A of output current across a broad voltage range from 1.2V to 37V, providing exceptional flexibility for circuit design.

Its operation is exceptionally user-friendly, requiring only two external resistors to set the desired output voltage precisely. This feature makes it an ideal choice for both prototyping and production, allowing designers to eliminate the need for stocking numerous fixed-voltage regulators.

To ensure maximum reliability and protection, the LM317BTG incorporates several key internal safeguards. These include internal current limiting, thermal overload protection, and output transistor safe-area compensation. These integrated features make the device inherently robust and essentially 'blow-out proof,' safeguarding both the regulator and the connected circuitry under fault conditions.

Its capability for floating operation makes it particularly suitable for high-voltage applications, where it can be used to regulate voltage above the common ground. The device's performance remains stable, with internal short-circuit current limiting that is constant across its operating temperature range from -40°C to 125°C.
