MAX8556, MAX8557
4A Ultra-Low-Input-Voltage LDO Regulators
Description
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 V
- 0.2V.
IN
Designed with an internal p-channel MOSFET pass transistor, the MAX8556/MAX8557 maintain 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 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.

... Note 1: Maximum power dissipation is obtained using JEDEC JESD51-5 and JESD51-7 standards. Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability ...

... PC board, copper traces, and the package materi- als. θ CA can be modified to increase the maximum power dissi- pation. The TQFN package has an exposed thermal pad on its underside. This pad provides a low thermal resistance path for heat transfer into the PC board. This low thermally resistive path carries a majority of the heat away from the IC ...
