The MAX8557ETE+T is a 4A ultra-low-input-voltage LDO regulator in 16 pin TQFN package. This LDO operates 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. It is designed with an internal P-channel MOSFET pass transistor and maintain a low 800μA typical supply current, independent of load current and dropout voltage. Using a P-channel MOSFET eliminates need for an additional external supply or a noisy internal charge pump. It offers a power-on reset output that transitions high 140ms after output has achieved 90% of its nominal output voltage. It is used in servers and storage devices, networking, base stations, optical modules, point-of-load supplies and ATE.
Input voltage range from 1.425V to 3.6V, output current of 4A
