MIC5366中文资料High Performance Single 150mA LDO w/ Auto Discharge数据手册Microchip规格书

描述 Description

The MIC5365/6 is an advanced general purpose linear regulator offering high power supply rejection (PSRR) in an ultra-small 1mm x 1mm package. The MIC5366 includes an auto-discharge feature that is activated when the enable pin is low. The MIC5365/6 is capable of sourcing 150mA output current and offers high PSRR, making it a great solution for any portable electronic application. Ideal for battery-powered applications, the MIC5365/6 offers 2% initial accuracy, low dropout voltage (180mV at 150mA), and low ground current (typically 32µA). The MIC5365/6 can also be put into a zero off-mode current state, drawing virtually no current when disabled. The MIC5365/6 is available in several advanced packages, occupying only 1mm2 of PCB area, a 75% reduction in board area compared to SC-70. It is also available in an SC-70-5 package. The MIC5365/6 has an operating junction temperature range of - 40°C to 125°C.

简介

MIC5366属于集成电路（IC）的线性+开关稳压器。由Microchip制造生产的MIC5366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。
