MIC5368中文资料High Performance 200mA Peak LDO w/ Auto Discharge数据手册Microchip规格书

描述 Description

The MIC5367/8 is an advanced, general purpose linear regulator offering high power supply rejection (PSRR) in an ultra-small 1.6mm x 1.6mm package. The MIC5368 includes an auto-discharge feature that is activated when the enable pin is low. The MIC5367/8 is capable of sourcing 200mA peak (150mA continous) output current and offers high PSRR, making it an ideal solution for any portable electronic application. Great for battery-powered applications, the MIC5367/8 offers 2% initial accuracy, low dropout voltage (180mV at 150mA), and low ground current (typically 29µA). The MIC5367/8 can also be put into a zero off-mode current state, drawing virtually no current when disabled. The MIC5367/8 has an operating junction temperature range of - 40°C to 125°C.

简介

MIC5368属于集成电路（IC）的线性+开关稳压器。由制造生产的MIC5368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。
