NCP700C数据手册集成电路（IC）的线性+开关稳压器规格书PDF

描述 Description

Noise sensitive RF applications such as Power Amplifiers in cell phones and precision instrumentation require very clean power supplies. The NCP700C is a 200 mA low dropout (LDO) linear voltage regulator that provides the engineer with a very stable, accurate voltage with ultra low noise and very high Power Supply Rejection Ratio (PSRR) suitable for RF applications. In order to optimize performance for battery operated portable applications, the NCP700C employs an advanced BiCMOS process to combine the benefits of low noise and superior dynamic performance of bipolar elements with very low ground current consumption at full loads offered by CMOS. Furthermore, in order to provide a small footprint for space-conscious applications, the NCP700C is stable with small, low value capacitors and is available in a very small WDFN6 1.5x1.5mm package.

简介

NCP700C属于集成电路（IC）的线性+开关稳压器。由制造生产的NCP700C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。
