NCP781中文资料Linear Voltage Regulator, 100 mA, 150 V, High PSRR数据手册ONSEMI规格书

描述 Description

The NCP781 is a very high−voltage tolerant linear regulator that offers the benefits of thermally enhanced DFN6 3.3 x 3.3 package and is able to withstand continuous DC or transient input voltages up to 150 V. The device is stable with small 0.1 uF Ceramic Output Capacitors which allows smaller PCB design at space constraining applications. The device features enable pin compatibility with standard CMOS logic.

特性 Features

• Wide Input Voltage Range: 6 V to 150 V
• ±2.5% Accuracy at Room Temperature
• Very Low Quiescent Current of Typ. 25 µA

应用 Application

• Led Lighting
• Bias Power Supplies
• Industrial Equipment

简介

NCP781属于集成电路（IC）的线性+开关稳压器。由制造生产的NCP781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。
