MIC37252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 MIC37252 is a 2.5A low-dropout linear voltage regulator that provides a low-voltage, high-current output with a minimum of external components. It offers high precision, low dropout, and low ground current.The MIC37252 operates from an input voltage of 3.0V to 6.0V. It is designed to drive digital circuits requiring low voltage at high currents (i.e., PLDs, DSP, microcontroller, etc.). It is available in an adjustable output voltage capable of 1.24V to 5.5V.Features of the MIC37252 LDO include thermal and current limit protection, and reverse current and reverse battery protection.Junction temperature range of the MIC37252 is -40°C to 125°C.For higher currents, see the MIC3730x family of LDOs.

简介

MIC37252属于集成电路（IC）的线性+开关稳压器。由制造生产的MIC37252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。
