LM317 3-TERMINAL ADJUSTABLE REGULATOR SLVS044H – SEPTEMBER 1997 – REVISED DECEMBER 2001 D D D D D D Output Voltage Range Adjustable From 1.2 V to 37 V Output Current Greater Than 1.5 A Internal Short-Circuit Current Limiting Thermal Overload Protection Output Safe-Area Compensation Package Options Include Plastic Small-Outline Transistor SOT-223 (DCY), Flange Mounted (KTE) and Heat-Sink Mounted (KC) Packages KC PACKAGE (TOP VIEW) INPUT OUTPUT ADJUST The OUTPUT terminal is in electrical contact with the mounting base. TO-220AB IO A description The LM317 is an adjustable three-terminal positive-voltage regulator capable of supplying more than 1.5 A over an output-voltage range of 1.2 V to 37 V. It is exceptionally easy to use and requires only two external resistors to set the output voltage. Furthermore, both line and load regulation are better than standard fixed regulators. The LM317 is packaged in the KC (TO-220AB) and KTE packages, which are easy to handle and use. In addition to having higher performance than fixed regulators, this device includes on-chip current limiting, thermal overload protection, and safe-operating-area protection. All overload protection remains fully functional, even if the ADJUST terminal is disconnected. The LM317 is versatile in its applications, including uses in programmable output regulation and local on-card regulation. Or, by connecting a fixed resistor between the ADJUST and OUTPUT terminals, the LM317 can function as a precision cur……
