MIC5232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 MIC5232 is an ultra-low quiescent current, low-dropout linear regulator that is capable of operating from a single-cell lithium ion battery. Consuming only 1.8µA of quiescent current while operating, the MIC5232 is ideal for stand-by applications like powering real-time clocks or memory in battery-operated electronics. The MIC5232 is capable of providing 10mA of output current and has low output noise, providing a small, efficient solution ideal for any keep-alive application including reverse current protection, keeping reverse leakage (VOUT > VIN) down to 20nA. The MIC5232 is a µCap design, operating with very small ceramic output capacitors for stability, reducing required board space and component cost. The MIC5232 is available in SOT-23-5 package with an operating junction temperature range of -40°C to 125°C.

简介

MIC5232属于集成电路（IC）的线性+开关稳压器。由制造生产的MIC5232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。
