MIC5265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 MIC5265 is a 150mA LDO in lead-free Thin SOT-23-5 packaging that is perfect for applications where cost is the priority. The MIC5265 is ideal for any application in portable electronics, including both RF and digital applications. With good output noise and high PSRR, the MIC5265 is ideal for noise sensitive applications such as RF. While the fast transient response and active shutdown circuitry makes it well-suited for powering digital circuitry.The MIC5265 has a 2.7V to 5.5V input operating voltage range, making it optimal for operation from a single-cell lithium ion battery or fixed 3.3V and 5V systems. The MIC5265 comes with an enable pin and can be put into a zero off-mode current state. The MIC5265 offers low dropout voltage (210mV at 150mA), low noise (57 µVrms), high PSRR, and integrates an active shutdown circuit on the output of each regulator to discharge the output voltage when disabled.

简介

MIC5265属于集成电路（IC）的线性+开关稳压器。由制造生产的MIC5265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。
