NCV8772C中文资料LDO Regulator, Ultra Low Iq with Enable and Reset, 350 mA数据手册ONSEMI规格书

描述 Description

The NCV8772C is 350 mA LDO regulator with integrated reset function dedicated for microprocessor applications. Its robustness allows NCV8772C to be used in severe automotive environments. Ultra low quiescent current as low as 18 µA typical makes it suitable for applications permanently connected to battery requiring ultra low quiescent current without load. This feature is especially critical when modules remain in active mode when ignition is off. The Enable function can be used for further decrease of quiescent current in shutdown mode to 1 µA. The NCV8772C contains protection functions as current limit, thermal shutdown and reverse output current protection.

简介

NCV8772C属于集成电路（IC）的线性+开关稳压器。由制造生产的NCV8772C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。
