汽车线性稳压器的最小静态电流

摘要：许多汽车的机械功能已被取代或修订近年来的电子电路。一个结果已经在微控制器，每车的数量迅速增加，类似的增长来自汽车电池生产中的总电流。只要车电机运行和发电机运转正常，这个功耗是不是一个问题。Maxim>AppNotes>AUTOMOTIVECIRCUITPROTECTIONVOLTAGEREFERENCESKeywords:Quiescentcurrent-LoadDumpOvervoltagePulse-Feb09,2007APPLICATIONNOTE3928AutomotiveLinearRegulatorsMinimizeQuiescentCurrentAbstract:Manyautomotivemechanicalfunctionshavebeenreplacedoramendedbyelectroniccircuitsinrecentyears.Oneconsequencehasbeenarapidincreaseinthenumberofmicrocontrollerspercar,producingasimilarincreaseinthetotalcurrentdrawnfromthecarbattery.Aslongthecarmotorisrunningandthealternatorisoperatingproperly,thispowerconsumptionisnotaconcern.Whenyouturnoffthemotor,however,thecarbatterymustimmediatelydeliverallcurrentsdemandedbythevarioussubsystems:
