MIC5206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 MIC5206 is an efficient linear voltage regulator with very low dropout voltage (typically 17mV at light loads and 165mV at 150mA) and very low ground current (600µA at 100mA output), with better than 1% initial accuracy. It has a logic-compatible enable/shutdown control input and an internal undervoltage monitor.Designed especially for handheld, battery-powered devices, the MIC5206 can be switched by a CMOS- or TTL-compatible logic signal. When disabled, power consumption drops nearly to zero. Dropout ground current is minimized to prolong battery life.Key features include an undervoltage monitor with an error flag output, a reference bypass pin to improve its already low-noise performance (8-pin versions only), reversed battery protection, current limiting, and over-temperature shutdown.The MIC5206 is available in several fixed voltages in a tiny SOT-23-5 package. It features a pinout, similar to the LP2980, but has significantly better performance. Fixed and adjustable output voltage versions, featuring the reference bypass option, are available in the 8-pin Micrel Mini 8® 8-pin MSOP (micro small-outline package).For low-dropout regulators that are stable with ceramic output capacitors, see the µCap MIC5255/MIC5256/MIC5247.

简介

MIC5206属于集成电路（IC）的线性+开关稳压器。由制造生产的MIC5206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。
