LM317DCYR Description

Short technical summary and product information.

The Texas Instruments LM317DCYR is a versatile, adjustable positive voltage regulator designed to provide a stable output voltage. It can handle an input voltage range from 3V to 40V and offers an adjustable output voltage between 1.25V and 37V. The device is capable of delivering a continuous output current of up to 1.5A.

Key features include internal current limiting, thermal overload protection, and safe operating area compensation, ensuring reliable operation under various conditions. The output voltage is set using only two external resistors, simplifying circuit design. For improved transient response, an optional output capacitor can be added.

This regulator is suitable for a wide range of applications, including programmable voltage sources and on-card regulation. It can also function as a precision current regulator when a fixed resistor is connected between the ADJUST and OUTPUT pins. The LM317DCYR is available in a surface-mount TO-261-4 package, facilitating integration into compact electronic designs.
