LM317KCS 三端可调稳压器

LM317KCS描述/ordering informationthe LM317是一种可调的三端正电压调节器，能够提供比1.5更大的输出电压范围1.25 V至37 V.It is exceptionally easy to use and requires only two external resistors to set the输出电压。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.通过连接调整和输出终端之间的固定电阻器，LM317功能作为精密电流调节器。一种可选择的输出电容器可被添加以改进传递性。该调节终端可被用于实现极高的反射比，这与标准的三终端调节器难以实现。
