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。

Automotive Linear Regulators Minimize Quiescent Current

Abstract: Many automotive mechanical functions have been replaced or amended by electronic circuits in
recent years. One consequence has been a rapid increase in the number of microcontrollers per car, producing
a similar increase in the total current drawn from the car battery. As long the car motor is running and the
alternator is operating properly, this power consumption is not a concern.

When you turn off the motor, however, the car battery must immediately deliver all currents demanded by the
various subsystems:
