LM317, NCV317 1.5 A Adjustable Output, Positive Voltage Regulator The LM317 is an adjustable 3−terminal positive voltage regulator capable of supplying in excess of 1.5 A over an output voltage range of 1.2 V to 37 V. This voltage regulator is exceptionally easy to use and requires only two external resistors to set the output voltage. Further, it www.onsemi.com employs internal current limiting, thermal shutdown and safe area compensation, making it essentially blow−out proof. The LM317 serves a wide variety of applications including local, on card regulation. This device can also be used to make a programmable output regulator, or by connecting a fixed resistor between the D2PAK−3 adjustment and output, the LM317 can be used as a precision current D2T SUFFIX regulator. 1 2 CASE 936 3 Features Heatsink surface (shown as terminal 4 in • Output Current in Excess of 1.5 A case outline drawing) is connected to Pin 2. • Output Adjustable between 1.2 V and 37 V • Internal Thermal Overload Protection • Internal Short Circuit Current Limiting Constant with Temperature • Output Transistor Safe−Area Compensation • Floating Operation for High Voltage Applications TO−220 • T SUFFIX Eliminates Stocking many Fixed Voltages CASE 221AB • Available in Surface Mount D2PAK−3, and Standard 3−Lead Transistor Package 1 Pin 1.

Load and line regulation are specified at constant junction temperature. Changes in VO due to heating effects must be taken into account separately. Pulse testing with low duty cycle is used. 4. Power dissipation within an IC voltage regulator produces a temperature gradient on the die, affecting individual IC components on the die. These effects can be minimized by proper integrated circuit design and layout techniques. Thermal Regulation is the effect of these temperature gradients on the output voltage and is expressed in percentage of output change per watt of power change in a specified time. 5. CAdj, when used, is connected between the adjustment pin and ground. 6. Thermal characteristics are not subject to production test. 7. Since Long−Term Stability cannot be measured on each device before shipment, this specification is an engineering estimate of average stability from lot to lot. www.onsemi.com 2
