什么是分立器件？一文讀懂它在智能設備中的作用
簡單來說，分立器件是具有單一電功能的電子元件，比如負責整流和穩壓的二極管、可用作放大和開關的三極管、用于高速開關的場效應管MOSFET、用于大功率控制的絕緣柵雙極型晶體管IGBT。它們不像集成電路IC那樣將多個功能單元集成在一片芯片上，而是以獨立個體的形式存在，但恰恰是這種獨立性，讓它們能在智能設備中承擔更精準、更靈活的功能任務。

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. -
