The Texas Instruments LM317MDT is a versatile adjustable positive voltage regulator IC. It is designed to provide a stable output voltage that can be precisely set by the user, ranging from 1.2V to 37V. This regulator is capable of supplying over 1.5A of load current, making it suitable for a wide array of power supply applications.
Key features include internal current limiting, thermal shutdown, and safe area compensation, which protect the device during fault conditions. The LM317MDT offers good line and load regulation, with typical values of 0.01% per volt and 0.5% of VO, respectively. Its reference voltage is typically 1.25V, with a temperature stability of 0.7%/VO.
This component is available in multiple package types, including TO-220-3L, SOT-223, and TO-252, allowing for flexibility in design and mounting. The TO-220 package is suitable for through-hole mounting, while SOT-223 and TO-252 are surface-mount options. The thermal resistance junction-to-case is a low 5℃/W, aiding in heat dissipation.
