LM317KCS描述/ordering informationthe LM317是一種可調的三端正電壓調節器，能夠提供比1.5更大的輸出電壓范圍1.25 V至37 V.It is exceptionally easy to use and requires only two external resistors to set the輸出電壓。Furtherre，both line and load regulation are better than standard fixed regulators.In addition to having higher performance than fixed regulators，this device includes on-chip current limiting，thermal overload protection，and safe operating-area protecAll overload protection remains fully functional，even if the adjust terminal is disconnected.The LM317 is vertatile in its applications，including uses in programme output regulation and local on-cardregulation.通過連接調整和輸出終端之間的固定電阻器，LM317功能作為精密電流調節器。一種可選擇的輸出電容器可被添加以改進傳遞性。該調節終端可被用于實現極高的反射比，這與標準的三終端調節器難以實現。
