MIC5377中文资料High Performance Low Dropout Single 150mA LDO数据手册Microchip规格书

描述 Description

The MIC5375/6/7/8 is an advanced general purpose linear regulator offering low dropout in an ultra-small package. When the MIC5376/8 is disabled, an internal resistive load is automatically applied to the output to discharge the output capacitor. The MIC5375/6/7/8 is capable of sourcing 150mA output current with low dropout, making it an ideal solution for any portable electronic application. Ideal for battery-powered applications, the MIC5375/6/7/8 offers 2% initial accuracy, low dropout voltage (120mV at 150mA), and low ground current (typically 29µA). The MIC5375/6/7/8 can also be put into a zero off-mode current state, drawing virtually no current when disabled. The MIC5375/6/7/8 has an operating junction temperature range of - 40°C to 125°C.

简介

MIC5377属于集成电路（IC）的线性+开关稳压器。由制造生产的MIC5377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。
