MIC5211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 MIC5211 is a dual µCap 80mA linear voltage regulator with very low dropout voltage (typically 20mV at light loads), very low ground current (225µA at 20mA output current), and better than 3% initial accuracy. This dual device comes in the miniature SOT-23-6 package, featuring independent logic control inputs.The µCap regulator design is optimized to work with low-value, low-cost ceramic capacitors. The outputs typically require only 0.1µF of output capacitance for stability.Designed especially for hand-held, battery powered devices, ground current is minimized using proprietary Super βeta PNP™ technology to prolong battery life. When disabled, power consumption drops nearly to zero.Key features include SOT-23-6 packaging, current limiting, overtemperature shutdown, and protection against reversed battery conditions.The MIC5211 is available in dual 1.8V, 2.5V, 2.7V, 2.8V, 3.0V, 3.3V, 3.6V, and 5.0V versions. Certain mixed voltages are also available.

简介

MIC5211属于集成电路（IC）的线性+开关稳压器。由制造生产的MIC5211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。
