CS8126数据手册集成电路（IC）的线性+开关稳压器规格书PDF

描述 Description

The CS8126 is a low dropout, high current 5V linear regulator. It is an improved replacement for the CS8156. Improvements include higher accuracy, tighter saturation control, better supply rejection, and enhanced circuitry. Familiar PNP regulator features such as reverse battery protection, over voltage shutdown, thermal shutdown, and current limit make the CS8126 suitable for use in automotive and battery operated equipment. Additional on chip filtering has been included to enhance rejection of high frequency transients on all external leads. RESET

简介

CS8126属于集成电路（IC）的线性+开关稳压器。由制造生产的CS8126稳压器 - 线性线性稳压器用于提供稳定的输出电压，无论负载电流、输入电压或环境因素如何变化，这些输出电压通常都要保持不变。它们的工作原理要求输入电压维持在高于所需的输出电压，而且要超出某个最小量，并且在工作时会将输入端的任何多余电压转换为热量。对于大多数应用而言，虽然这种稳压器的效率低于开关模式的稳压器，但它们通常更适合对噪声高度敏感的应用。
