描述 Description

The NCV8674 is a precision 5.0 V or 12 V fixed output, low dropout integrated voltage regulator with an output current capability of 350 mA. Careful management of light load current consumption, combined with a low leakage process, achieve a typical quiescent current of 30 µA.The output voltage is accurate within ±2.0%, and maximum dropout voltage is 600 mV at full rated load current.It is internally protected against input supply reversal, output overcurrent faults, and excess die temperature. No external components are required to enable these features.

简介

NCV8674属于集成电路（IC）的线性+开关稳压器。由制造生产的NCV8674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。
