MAX8556, MAX8557 4A Ultra-Low-Input-Voltage LDO Regulators

The MAX8556 MAX8557 low-dropout linear Regulators operate from input voltages as low as 1.425V and are 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 MAX8556 MAX8557 maintain a low 800A 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 MAX8556 features a POK output that transitions high when the Regulator output is within 10% of its nominal output voltage. The MAX8557 offers a power-on reset output that transitions high 140ms after the output has achieved 90% of its nominal output voltage.
The MAX8556 MAX8557 are available in a 16-pin thin QFN 5mm x 5mm package with exposed paddle.
