MIC5353中文资料6Vin, Single 500mA ULDO数据手册Microchip规格书

描述 Description

The MIC5353 is a high performance, single-output, ultra-low LDO (ULDO™) regulator, offering a low total output noise of 30µVrms. The MIC5353 is capable of sourcing 500mA output current and offers high PSRR and low output noise, making it an ideal solution for RF applications. The MIC5353 provides 2% accuracy, extremely low dropout voltage (160mV at 500mA), and low ground current (typically 90µA) making it ideal for battery-operated applications. When disabled, the MIC5353 enters a zero off-mode current state, thereby drawing almost no current.

简介

MIC5353属于集成电路（IC）的稳压器-线性。由制造生产的MIC5353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。
