MIC5301中文资料150mA Single LDO数据手册Microchip规格书

描述 Description

The MIC5301 is a high performance, single output ultra-low LDO (ULDO) regulator, offering low total output noise. The MIC5301 is capable of sourcing 150mA output current and offers high PSRR and low output noise, making it an ideal solution for RF applications.For battery-operated applications, the MIC5301 offers 2% accuracy, extremely low dropout voltage (40mV at 150mA), and low ground current (typically 85µA total). The MIC5301 can also be put into a zero off-mode current state, drawing no current when disabled.The MIC5301 is available in the 1.6mm x 1.6mm MLF® package, occupying only 2.56mm2 of PCB area, a 36% reduction in board area compared to SC-70 and 2mm x 2mm MLF® packages.The MIC5301 has an operating junction temperature range of -40°C to +125°C and is available in fixed and adjustable output voltages in lead-free (RoHS-compliant) MLF® and Thin SOT-23-5 packages.

简介

MIC5301属于集成电路（IC）的线性+开关稳压器。由Microchip制造生产的MIC5301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。
