1.5A Adjustable Positive Voltage Regulator TL317 1.5A Adustable Positive Voltage Regulator General Description z The TL317 is adjustable 3-terminal positive voltage regulator capable of supplying in excess of 1.5A over a 1.25V to 37V output range. This is exceptionally easy to use and require only two external resistors to set the output voltage. Further, both line and load regulation are better than standard fixed regulators. z The TL317 is available in standard SOT-223, D-PACK, TO-220 and D2-PACK packages. SOT-223 TO-220 D-PACK (TO-252) D2-PACK (TO-263) Features z Adjustable output between 1.25V and 37V z Guaranteed 1.5A output current z Line regulation typically 0.001%/V z Load regulation typically 0.1% z 80dB ripple rejection (with Cadj) z Internal thermal overload protection z Internal short-circuit current limiting z Output transistor safe-area compensation z RoHS compliance Ordering Information 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.
