Monolithic Power Systems, Inc. Voltage Regulators - Linear MP6401DJ-18BD3-LF-P

The MP6401DJ-18BD3-LF-P is a low-dropout linear voltage regulator designed to operate with input voltages ranging from 2.5V to 5.5V. It provides a regulated output voltage of 1.8V with an accuracy of ¬±2% and can deliver up to 300mA of load current. This device features a low quiescent current of 80OºA, making it suitable for battery-powered applications. The regulator has a low dropout voltage of 114mV at maximum load, ensuring efficient operation. Additionally, the MP6401 includes an integrated reset circuit that activates when the output voltage falls below a specified threshold, with options for reset delay times of 3.125ms, 25ms, 200ms, and 1580ms. It is available in compact package options including TSOT23-6, and is rated for operation in temperatures from -40¬8C to 85¬8C. The device also incorporates protection features such as input reverse current, thermal shutdown, and short-circuit protection, making it a robust choice for applications in portable devices like smartphones, PDAs, and GPS units.
