MIC5280数据手册集成电路（IC）的线性+开关稳压器规格书PDF

描述 Description

The MIC5280 is a high performance, low dropout regulator, offering a very low noise output with a very wide input voltage operating range, up to 120V DC input voltage.Ideal for high input voltage applications such as industrial and telecom, the MIC5280 offers 2% initial accuracy, extremely high power supply rejection ratio (PSRR >80dB) and low ground current (typically 31µA). The MIC5280 can also be put into a zero off-mode current state, drawing a minuscule amount of current when disabled.The MIC5280 has a very wide input voltage range, with a DC rating from -24V to 120V. The MIC5280 is optimized for line transient response, making it ideal for harsh environment applications.The MIC5280 has an operating junction temperature range of -40°C to +125°C and is available in an adjustable output voltage version in a lead-free (RoHS-compliant) 8-pin ePad SOIC packaging.

简介

MIC5280属于集成电路（IC）的线性+开关稳压器。由制造生产的MIC5280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。
