Monolithic Power Systems, Inc. Voltage Regulators - Linear MP6401DGT-25AD3-LF-Z

The MP6401DGT-25AD3-LF-Z is a low-dropout linear voltage regulator that operates with an input voltage range of 2.5V to 5.5V and provides a regulated output voltage of 2.5V with an accuracy of ¬±2%. It is capable of delivering up to 300mA of load current, making it suitable for various portable applications such as smartphones, PDAs, and GPS devices. The device features a low quiescent current of 80OºA, a dropout voltage of 114mV at 300mA, and an ultra-low noise output of 15OºV RMS. Additionally, the MP6401 includes an integrated reset circuit that asserts a push-pull active-low signal when the output voltage drops below a specified threshold, with four selectable reset delay times of 3.125ms, 25ms, 200ms, and 1580ms. It is available in compact package options including TQFN6 (2mm x 2mm) and is rated for operation in a temperature range of -40¬8C to 85¬8C. The device also incorporates protection features such as input reverse current, thermal shutdown, and short-circuit protection, enhancing its reliability in various applications.
