LM317MQDCYR Description

Short technical summary and product information.

The LM317MQDCYR from Texas Instruments is an adjustable, positive-voltage linear regulator designed for automotive applications. It is capable of supplying an output current of up to 500mA over an adjustable output voltage range of 1.25V to 37V. This device requires only two external resistors to set the output voltage, simplifying circuit design.

 

Key electrical characteristics include a typical line regulation of 0.01% and a typical load regulation of 0.1%. The regulator incorporates built-in protection features such as short-circuit current limiting and thermal overload protection, ensuring reliable operation. It is also stable without requiring an external output capacitor.

 

The LM317MQDCYR is AEC-Q100 qualified for automotive applications and operates within a junction temperature range of -40°C to +125°C. It is supplied in a 4-pin SOT-223 surface-mount package, with a standard package quantity of 2,500 units on tape and reel.
