MIC5283中文资料120Vin 150mA Ultra-Low Iq High-PSRR LDO数据手册Microchip规格书

描述 Description

The MIC5283 high-performance linear regulator offers a very-wide input operating voltage range, up to 120V DC, and supplies an output current of up to 150mA. Ideal for high input voltage applications such as industrial and telecom, the MIC5283 offers ±3% initial accuracy, extremely high-power supply rejection ratio (75dB at 10kHz) and an ultra-low quiescent current of 8µA. The MIC5283 is optimized for high-voltage line transients, making it ideal for harsh environment applications.The MIC5283 is offered in both fixed output voltage (3.3V or 5.0V) and adjustable output voltage (1.22V to 5.5V) options. The MIC5283 operates over a -40°C to +125°C temperature range and is available in lead-free, RoHS-compliant, and ePad SOIC-8 packages.

简介

MIC5283属于集成电路（IC）的线性+开关稳压器。由制造生产的MIC5283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。
