NCV8509中文资料Sequenced Linear Dual-Voltage Regulator数据手册ONSEMI规格书

描述 Description

The NCV8509 Series are dual voltage regulators whose output voltages power up in such a manner as to protect the integrity of modern day microcontroller I/O and ESD input structures. Newer generation microcontrollers require two power supplies. One voltage is used for powering the core, while the other powers the I/O.Power up sequencing of these dual voltages is crucial to ensure the integrity of the microprocessor.

简介

NCV8509属于集成电路（IC）的线性+开关稳压器。由制造生产的NCV8509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。
