MIC5200中文资料100mA, 1% Accuracy LDO Regulator数据手册Microchip规格书

描述 Description

The MIC5200 is an efficient linear voltage regulator with very low dropout voltage (typically 17mV at light loads and 200mV at 100mA) and very low ground current (1mA at 100mA output), offering better than 1% initial accuracy with a logic-compatible on/off switching input. Designed especially for handheld battery powered devices, the MIC5200 is switched by a CMOS- or TTL-compatible logic signal. The enable control may be tied directly to VIN if unneeded. When disabled, power consumption drops nearly to zero. The ground current of the MIC5200 increases only slightly in dropout, further prolonging battery life. Key MIC5200 features include protection against reversed battery, current limiting, and over-temperature shutdown.The MIC5200 is available in several fixed voltage and accuracy configurations.

简介

MIC5200属于集成电路（IC）的线性+开关稳压器。由制造生产的MIC5200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。
