300mA, AEC-Q100-Compliant LDO Targeted At Automotive Applications

Micrel Inc. recently announced a new automotive AEC-Q100 qualified high-performance low-dropout voltage regulator (LDO) featuring an ultralow dropout of only 100mV at 300mA. The MAQ5300 comes in a tiny 2mm x 2mm DFN package and is ideal for space-constrained and high-reliability applications that are subjected to the harsh environments and temperatures often encountered in automotive and industrial applications. The MAQ5300 is currently available in volume, and pricing starts at $0.39 for 1K quantity.

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, 3.0V, and 3.3V. Other features include an initial precise output voltage accuracy of ±2 percent, 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.
