0.5A Adjustable Positive Voltage Regulator LM317M 0.5A Adjustable Positive Voltage Regulator General Description z LM317M is an adjustable 3-terminal positive voltage regulator capable of supplying in excess of 0.5A over an output range of 1.2V to 37V. LM317M is exceptionally easy to use and requires only two external resistors to set the output voltage.Furthermore,both line regulation and load regulation are better than fixed voltage regulators,Additionally,the LM317M include on-chip current limiting, thermal overload protection and safe-operating-area protection. TO-220 z z SOT-223 LM317M Series are available in TO-220,SOT-223 and DPAK (TO-252) packages. DPAK (TO-252) Features Adjustable Output Voltage from 1.2V to 37V z Output Current in excess of 0.5A z Input-Output Voltage Differencial:40V (Max) z Line regulation: typical 0.01%/V z Load regulation:typical 0.1% z Internal Thermal Overload Protection z Internal Short-circuit Current Limiting z Output transistor safe operation area (SOA) compensation z Floating operation for high voltage applications z RoHS compliance and Halogen free z Applications: PC Mother Board z Graphic Card z NIC/Switch z LCD Monitor , DVD Video Player and Printer z Telecom Equipment and other Peripheral Equipment z TAITRON COMPONENTS INCORPORATED www.taitroncomponents.com Tel: Fax: (800)-TAITRON (800)-824-8766 (800)-TAITFAX (800)-824-8329 (661)-257-6060 (661)-257-6415 Rev.
