Product Summary

The MAX8556ETE+T is a low-dropout linear regulator. It operates from input voltages as low as 1.425V and is able to deliver up to 4A of continuous output current with a typical dropout voltage of only 100mV. The output voltage is adjustable from 0.5V to VIN - 0.2V. Designed with an internal p-channel MOSFET pass transistor, the MAX8556ETE+T maintains a low 800µA typical supply current, independent of the load current and dropout voltage. Using a p-channel MOSFET eliminates the need for an additional external supply or a noisy internal charge pump. Other features include a logic-controlled shutdown mode, built-in soft-start, short-circuit protection with foldback current limit, and thermal-overload protection. The MAX8556ETE+T features a POK output that transitions high when the regulator output is within ±10% of its nominal output voltage. The MAX8556ETE+T is available in a 16-pin thin QFN 5mm x 5mm package with exposed paddle.
