Micrel MAQ5300 is designed as an automotive-qualified, ultra-small, ultra-low dropout CMOS regulator (ULDO). The AEC-Q100 qualified MAQ5300 LDO is ideally suited for the most demanding automotive applications including infotainment, camera module, image sensors, and anywhere with limited PCB space. MAQ5300 offers an extremely low dropout voltage of 100mV at 300mA, very low output noise 120µVRMS, and can operate from a 2.3V to 5.5V input while delivering up to 300mA output current. The device offers 2% initial accuracy, low ground current (typically 85µA total), thermal shutdown, and current-limit protection. The MAQ5300 can go into a zero-off-mode current state, drawing no current when disabled. The MAQ5300 is available in a lead-free (RoHS-compliant) 6-pin 2mm × 2mm DFN package with an operating junction temperature range of -40°C to +125°C.
