NCV8501数据手册集成电路（IC）的线性+开关稳压器规格书PDF

描述 Description

The NCV8501 is a family of precision micropower voltage regulators with 150mA output current capability. The family has output voltage options for adjustable, 2.5 V, 3.3 V, 5.0 V, 8.0 V, and 10 V that are accurate within ±2.0%. Maximum dropout voltage reaches 0.6 V at full load. Low quiescent current is a feature drawing only 90µA with a 100µA load. This part is ideal for all battery operated microprocessor equipment. Microprocessor control logic includes an active RESET (with DELAY), and a flag monitor which can be used to provide an early warning signal to the microprocessor of a potential impending RESET signal. The use of the flag monitor allows the microprocessor to finish any signal processing before the RESET shuts the microprocessor down.The active RESET circuit operates correctly at an output voltage as low as 1.0 V. The RESET function is activated during the power up sequence or during normal operation if the output voltage drops outside the regulation limits.The regulator is protected against reverse battery, short circuit, and thermal overload conditions. The device can withstand load dump transients making it suitable for use in automotive environments.

简介

NCV8501属于集成电路（IC）的线性+开关稳压器。由制造生产的NCV8501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。
