MIC5236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 MIC5236 is a low quiescent current, µCap low dropout regulator. With a maximum operating input voltage of 30V and a quiescent current of 20µA, it is ideal for supplying keep-alive power in systems with high-voltage batteries.Capable of 150mA output, the MIC5236 has a dropout voltage of only 300mV. It can also survive an input transient of -20V to +60V.As a µCap LDO, the MIC5236 is stable with either a ceramic or a tantalum output capacitor. It only requires a 1.0µF output capacitor for stability.The MIC5236 includes a logic-compatible enable input and an undervoltage error flag indicator. Other features of the MIC5236 include thermal shutdown, current-limit, overvoltage shutdown, load-dump protection, reverse leakage protection, and reverse battery protection.Available in the thermally enhanced SOIC-8 and MSOP-8 packages, the MIC5236 comes in fixed 2.5V, 3.0V, 3.3V, 5.0V, and adjustable voltages.

简介

MIC5236属于集成电路（IC）的线性+开关稳压器。由制造生产的MIC5236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。
