TEXAS INSTRUMENTS LM317MQDCYR Adjustable Linear Voltage Regulator, 500mA, SOT-2

The TEXAS INSTRUMENTS LM317MQDCYR is a versatile, 3-terminal adjustable positive linear voltage regulator, designed to deliver a stable and reliable power supply for a wide range of electronic applications. Capable of supplying more than 500mA over a broad output voltage range of 1.25V to 37V, it offers exceptional flexibility and ease of use, requiring only two external resistors to set the desired output level. This regulator outperforms standard fixed types with superior line and load regulation, ensuring consistent performance even with fluctuations in input voltage or load conditions.

Engineered for robust operation, the LM317M incorporates comprehensive on-chip protection features including internal short-circuit current limiting, thermal-overload protection, and safe-operating-area compensation. These safeguards remain fully functional even if the ADJUST terminal becomes disconnected, providing an added layer of reliability. As a floating regulator with no device ground terminal, its quiescent current is efficiently directed to the load rather than being wasted, enhancing overall efficiency.

This component is suitable for creating high-voltage regulated outputs, capable of reaching hundreds of volts, provided the maximum input-to-output differential does not exceed 40V at any time. Its design also allows it to be configured as a precise floating current source controlled by a single external resistor. The device is constructed as a green product, free from antimony and bromine (Sb/Br), aligning with environmentally conscious manufacturing practices.
