MIC5233-3.3YS集成电路（IC）的线性+开关稳压器规格书PDF中文资料

MIC5233-3.3YS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MIC5233-3.3YS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 MIC5233 is a 100 mA, 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 MIC5233 ideal for multicell Li-Ion battery systems.

A μCap LDO design, the MIC5233 is stable with either ceramic or tantalum output capacitors. It only requires a 2.2 μF output capacitor for stability.

Features of the MIC5233 include enable input, thermal shutdown, current limit and reverse battery protection, and reverse leakage protection.

Available in fixed and adjustable output voltage versions, the MIC5233 is offered in the 5-lead SOT23 and 3-lead SOT223 packages with a junction temperature range of –40°C to +125°C.
