MP6401
300mA LDO Linear Regulator with
Integrated Reset Circuit
The Future of Analog IC Technology
DESCRIPTION
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.
