NCV8182C中文资料Micropower 200 mA Low Dropout Tracking Regulator/Line Driver数据手册ONSEMI规格书

描述 Description

The NCV8182C is a monolithic integrated low dropout tracking regulator designed to provides an adjustable buffered output voltage that closely tracks the reference input.The output delivers up to 250 mA while being able to be configured higher, lower or equal to the reference voltages. The device has been designed to operate over a wide input and VREF/EN operating voltage range while still maintaining excellent DC characteristics. The NCV8182C is protected from reverse battery, short circuit and thermal runaway conditions. The device also can withstand load dump transients and reverse polarity input voltage transients. This makes it suitable for use in automotive environments. The VREF/EN lead serves two purposes. It is used to provide the input voltage as a reference for the output and it also can be pulled low to place the device in sleep mode.

简介

NCV8182C属于集成电路（IC）的线性+开关稳压器。由制造生产的NCV8182C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。
