MAX8556ETE+T

The MAX8556ETE+T is a 4A ultra low input voltage LDO regulator in 16 pin TQFN package. This LDO operate from input voltage 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 IC maintain a low 800µA typical supply current, independent of the load current and dropout voltage. Using a P-channel MOSFET eliminates need for an additional external supply or a noisy internal charge pump. It features a POK output that transitions high when the regulator output is within ±10% of its nominal output voltage. It is used in servers and storage devices, networking, base stations, optical modules, point-of-load supplies and ATE.
