In the other direction, driving a 3.3V input from a 5V output you might expect that a level shifting circuit would be required, and in many cases you would be right. But before reaching for that ...

01 使用LDO稳压器 标准三端线性稳压器的压差通常是 2.0-3.0V。要把 5V 可靠地转换为 3.3V，就不能使用它们。压差为几百个毫伏的低压降 （Low Dropout， LDO）稳压器，是此类应用的理想选择。图 1-1 是基本LDO 系统的框图，标注了相应的电流。 从图中可以 ...
