MIC5207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 MIC5207 is an efficient linear voltage regulator with ultra-low-noise output, very low dropout voltage (typically 17mV at light loads and 165mV at 150mA), and very low ground current (720µA at 100mA output). The MIC5207 offers better than 3% initial accuracy.Designed especially for hand-held, battery-powered devices, the MIC5207 includes a CMOS or TTL compatible enable/shutdown control input. When in shutdown, power consumption drops nearly to zero.Key MIC5207 features include a reference bypass pin to improve its already low-noise performance, reversed-battery protection, current limiting, and over temperature shutdown.The MIC5207 is available in fixed and adjustable output voltage versions in a small SOT-23-5 package. For low-dropout regulators that are stable with ceramic output capacitors, see the µCap MIC5245/6/7 family.

简介

MIC5207属于集成电路（IC）的线性+开关稳压器。由制造生产的MIC5207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。
