MAQ5300中文资料Ultra low dropout CMOS regulator (ULDO)数据手册Microchip规格书

描述 Description

The MAQ5300 is an automotive-qualified, ultra-small, ultra low dropout CMOS regulator (ULDO) that is ideal for today's most demanding automotive applications including infotainment, camera module, image sensors, and anywhere PCB space is limited. It offers extremely low dropout voltage, very low output noise and can operate from a 2.3V to 5.5V input while delivering up to 300mA. The MAQ5300 offers 2% initial accuracy, low ground current (typically 85µA total), thermal shutdown, and current-limit protection. The MAQ5300 can also be put into a zero-off-mode current state, drawing no current when disabled. The MAQ5300's operating junction temperature range is -40°C to +125°C and it is available in fixed output voltages in a lead-free (RoHS-compliant) 6-pin 2mm x 2mm DFN package.

简介

MAQ5300属于集成电路（IC）的线性+开关稳压器。由制造生产的MAQ5300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。
