NCP4680中文资料NCP4680: Linear Voltage Regulator, LDO, Low Noise, 150 mA数据手册ONSEMI规格书

描述 Description

The NCP4680 is a CMOS Linear Voltage Regulator with 150 mA output current capability. The device is available in a tiny 0.8x0.8 mm XDFN, and has high output voltage accuracy, low supply current and high ripple rejection. The NCP4680 is easy to use and includes output current fold-back protection. A Chip Enable function is included to save power by lowering supply current. The line and load transient responses are very good, making this regulator ideal for use as a power supply for communication equipment.

简介

NCP4680属于集成电路（IC）的线性+开关稳压器。由ONSEMI制造生产的NCP4680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。
