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 ...

Over the years, we’ve seen some modern microcontrollers turn out to be 5V-tolerant – now, RP2040 joins the crowd. Half a year ago, when we covered an ISA card based on a Pi Pico, [Eben Upton ...

We don’t mean just a low voltage either, probing with his meter, he became increasingly convinced that the 5 V pin on the module’s IP5306 ... Raspberry Pi 4’s power supply helped reduce ...
