MIC5235-1.8BM5集成电路（IC）的线性+开关稳压器规格书PDF中文资料

MIC5235-1.8BM5属于集成电路（IC）的线性+开关稳压器。由美国微芯科技公司制造生产的MIC5235-1.8BM5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。

General Description

The MIC5235 is a 150mA highly accurate, low dropout

regulator with high input voltage and ultra-low ground

current. This combination of high voltage and low ground

current makes the MIC5235 ideal for USB and portable

electronics applications, using 1-cell, 2-cell or 3-cell Li-Ion

battery inputs.

A µCap LDO design, the MIC5235 is stable with either

ceramic or tantalum output capacitor. It only requires a

2.2µF capacitor for stability.

Features of the MIC5235 includes enable input, thermal

shutdown, current limit, reverse battery protection, and

reverse leakage protection.

Available in fixed and adjustable output voltage versions,

the MIC5235 is offered in the IttyBitty®

SOT-23-5 package

with a junction temperature range of –40°C to +125°C.
