本文略述三端固定电压集成稳压器W7800和W7900系列产品的优点。参考有些生产厂家产品目录,讨论其中介绍的采用3CG3保护外附功率调整管的扩大电流电路,并在这种稳压器芯片内部固有的保护功能基础上,提出直接保护和二极管保护外附功率调整管稳压电路。
This article outlines the benefits of the three-terminal, fixed voltage integrated voltage regulator W7800 and W7900 Series. Refer to the catalogs of some manufacturers to discuss the extended current circuit using the 3CG3 protection power conditioning tube introduced therein and propose the direct protection and diode protection power adjustment based on the intrinsic protection function of the regulator chip Regulator circuit.
