NCP186中文资料Linear Voltage Regulator, Fast Transient Response, 1 A with Enable数据手册ONSEMI规格书

描述 Description

The NCP186 is a Very Low Dropout Regulator which provides up to 1 A of load current and maintains excellent output voltage accuracy of 1.0 % in -40 to 85degC range. The operating input voltage range from 1.8 V up to 5.5 V makes this device suitable for Li−ion battery powered products as well as post−regulation applications. The product is available in several fixed output voltage option and others are possible on request in range from 1.2 V to 3.9 V. NCP186 is fully protected against overheating and output short circuit.
Small 8−pin XDFN6 1.2 mm x 1.6 mm package makes the device especially suitable for space constrained applications.

简介

NCP186属于集成电路（IC）的线性+开关稳压器。由ONSEMI制造生产的NCP186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。
