MIC5202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 MIC5202 is a dual linear voltage regulator with low dropout voltage (typically 17mV at light loads and 210mV at 100mA), and low ground current (1mA at 100mA per output). Ideal for battery-operated applications, the MIC5202 offers 1% output voltage accuracy and dual enable pins. The enable pins may be driven individually or tied directly to VIN. When the part is disabled, power consumption drops to nearly zero. The MIC5202 ground current increases slightly in dropout, which minimizes power consumption and increases battery life. Some key features include reversed battery protection, current limit, and overtemperature protection.The MIC5202 is available in fixed output voltages in the small 8-pin SOIC package.

简介

MIC5202属于集成电路（IC）的线性+开关稳压器。由制造生产的MIC5202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。
