LM117 LM317A LM317 3-Terminal Adjustable Regulator
General Description
The LM117 series of adjustable 3-terminal positive voltage regulators is capable of supplying in excess of 1 5A over a 1 2V to 37V output range They are 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 Also the LM117 is packaged in standard transistor packages which are easily mounted and handled In addition to higher performance than fixed regulators the LM117 series offers full overload protection available only in IC’s Included on the chip are current limit thermal overload …ver más…
