MIC35302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 MIC35302 is a 3A low-dropout linear voltage regulator that provides a low voltage, high current output with a minimum of external components. It offers high precision, ultra-low dropout (600mV over temperature), and low ground current.The MIC35302 operates from an input of 2.25V to 6.0V. It is designed to drive digital circuits requiring low voltage at high currents (i.e., PLDs, DSPs, micro-controllers, etc.), providing an adjustable output voltage from 1.24V to 5.4V.Features of the MIC35302 LDO include current limiting and thermal protection, and reverse current and reverse battery protection. Also a logic (active-HIGH) enable pin is included. The MIC35302 is available in a 5-pin power D-Pak package (TO-252) with an operating temperature range of -40°C to +125°C.

简介

MIC35302属于集成电路（IC）的线性+开关稳压器。由制造生产的MIC35302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。
