Device Overview

Summary

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.
