NCV4299C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 NCV4299C is a family of precision micropower voltage regulators with an output current capability of 150 mA. It is available in 5.0 V or 3.3 V output voltage.
The output voltage is accurate within ±2% with a maximum dropout voltage of 0.5 V at 100 mA. Low Quiescent current is a feature drawing only 80 µA with a 100 µA load. This part is ideal for
any and all battery operated microprocessor equipment.
The device features microprocessor interfaces including an adjustable reset output and adjustable system monitor to provide shutdown early warning. An inhibit function is available. With inhibit active, the regulator turns off and the device consumes less than 1.0 µA of quiescent current.
The part can withstand load dump transients making it suitable for use in automotive environments.

简介

NCV4299C属于集成电路（IC）的线性+开关稳压器。由制造生产的NCV4299C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。
