MIC61150中文资料Low VIN, Single Supply, 1.5A LDO数据手册Microchip规格书

描述 Description

MIC61150 is a 1.5A output, low input voltage, single-supply regulator. This regulator operates over a single input voltage range of 1.1V to 3.6V and offers an ultra-low dropout less than 200mV over the entire operating temperature range. The MIC61150 is designed to drive digital circuits requiring low voltages at high currents such as DSPs, FPGAs, microcontrollers, etc. The regulator is available as a 1.0V fixed-output voltage option or as an adjustable-output voltage option. The MIC61150 is stable with a 22µF low-ESR ceramic output capacitor and includes protection features such as thermal shutdown, current limiting and logic enable. The MIC61150 has an operating junction temperature range of -40°C to +125°C.

简介

MIC61150属于集成电路（IC）的线性+开关稳压器。由制造生产的MIC61150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。
