描述 Description

The NCV8702 is a 200 mA Ultra-Low Quiescent Current, Low Dropout Linear Voltage Regulator with Ultra Low Noise characteristics. It's low noise combined with high Power Supply Rejection Ratio (PSRR) make it especially suited for use in RF, audio or imaging applications. The device is manufactured in an advanced BiCMOS process to provide a powerful combination of low current consumption and excellent noise performance. The NCV8702 is stable with small, low value 1µ capacitors allowing designers to minimise the total PCB space occupied by the solution. The device is packaged in a small 1.5x1.5mm xDFN6 package as well as in a TSOP-5 package.

简介

NCV8702属于集成电路（IC）的线性+开关稳压器。由制造生产的NCV8702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。
