NCP2860中文资料NCP2860: 300 mA Low Noise, Low Dropout Linear Voltage Regulator数据手册ONSEMI规格书

描述 Description

The NCP2860 is a low noise, low dropout linear regulator that can drive 300 mA from a 3.0 V to 6.0 V input. It is offered with an adjustable output between 1.25 V to 5.8 V and in a fixed output voltage of 2.77 V. Along with Thermal Overload and Short Circuit Protection, the device has several useful features such as a Shutdown function, a Fault indicator and a Soft Start capability. The excellent performances that the NCP2860 features in terms of transient response, PSRR and noise make it an ideal solution for audio applications (e.g. audio amplifier drivers).

简介

NCP2860属于集成电路（IC）的线性+开关稳压器。由ONSEMI制造生产的NCP2860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。
