Micrel Inc. has introduced an automotive AEC-Q100 qualified high-performance low-dropout voltage regulator (LDO) featuring an ultralow dropout of only 100mV at 300mA. According to the company, the MAQ5300 comes in a tiny 2mm x 2mm DFN package and is geared for space-constrained and high-reliability applications that are subjected to the harsh environments and temperatures such as automotive and industrial applications.


"As the number of sensors in vehicles increases due to continued developments in the connected-car, the need for smaller power solutions also increases," noted Brian Hedayati, VP of marketing for high performance linear and power solutions at Micrel. "The MAQ5300 provides a perfect solution for size-critical applications with minimal PCB board space including the rapidly growing market for front/rear/side-view camera modules and image sensors."

The MAQ5300 is fully compliant to the AEC-Q100 quality specifications and is supported with the requisite PPAP qualification data. The device features 300mA guaranteed output current and is available in numerous fixed output voltage options of 1.5V, 1.8V, 2.5V, 2.8V, 2.85V, 3V and 3.3V. Other features include an initial precise output voltage accuracy of two per cent, low shutdown quiescent current of 0.1µA, thermal shutdown and current limit protection. The solution is packaged in a tiny 6-pin 2mm x 2mm DFN package.

The MAQ5300 is available in volume, and pricing starts at $0.39 for 1K quantity.
