MP6401DJ-33AD3-LF-Z

The MP6401 combines a low-dropout linear regulator with an integrated reset circuit. It operates from a 2.5V to 5.5V input voltage and regulates the output voltage with 2% accuracy at 1.8V, 2.5V, 3.3V or adjustable value. It delivers up to 300mA of load current. By combining an LDO linear regulator with a reset circuit, these products can reduce cost and save space in compact portable devices such as cell phones, smart phones, PDAs, PMPs, and portable GPS devices. The MP6401 provides a push-pull, active-low that asserts when the regulator output voltage drops below the microprocessor supply threshold (-7.5% or -12.5% of nominal output voltage). Four reset delay time, 3.125ms, 25ms, 200ms and 1580ms can be selected. The MP6401 is available in 3mmx3mm TQFN8, 2mmx2mm TQFN6 and TSOT packages and is specified for operation from -40°C to 85°C.
