什么是分立器件？一文读懂它在智能设备中的作用
简单来说，分立器件是具有单一电功能的电子元件，比如负责整流和稳压的二极管、可用作放大和开关的三极管、用于高速开关的场效应管MOSFET、用于大功率控制的绝缘栅双极型晶体管IGBT。它们不像集成电路IC那样将多个功能单元集成在一片芯片上，而是以独立个体的形式存在，但恰恰是这种独立性，让它们能在智能设备中承担更精准、更灵活的功能任务。

LN6216 Output Current CMOS Regulator with Low Power and Low Differential
LN6216 series is a positive voltage regulator with low voltage difference, high precision output voltage and low current consumption developed by using CMOS technology. Due to the built-in low on state resistance transistor, the voltage difference is low and the output current is large. In order to make the load current not exceed the current capacity of the output transistor, overload current protection circuit and short circuit protection circuit are built in. High density installation is possible due to small packages such as SOT89-3L, SOT23-3L, SOT23-3B. -
