4A Ultra-Low-Input-Voltage  
LDO Regulators  
6/MAX857  
General Description  
Features  
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 out-  
o 1.425V to 3.6V Input Voltage Range  
o Guaranteed 4A Output Current  
o
1% Output Accuracy Over Load/Line/  
Temperature  
o 100mV Dropout at 4A Load (typ)  
o Built-In Soft-Start  
put voltage is adjustable from 0.5V to V - 0.2V.  
IN  
Designed with an internal p-channel MOSFET pass tran-  
sistor, the MAX8556/MAX8557 maintain a low 800µA typi-  
cal 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 inter-  
nal charge pump. Other features include a logic-con-  
trolled shutdown mode, built-in soft-start, short-circuit  
protection with foldback current limit, and thermal-over-  
load protection. The MAX8556 features a POK output that  
transitions high when the regulator output is within 10ꢀ  
of its nominal output voltage. The MAX8557 offers a  
power-on reset output that transitions high 140ms after the  
output has achieved 90ꢀ of its nominal output voltage.  
o 800µA (typ) Operating Supply Current  
o 150µA (max) Shutdown Supply Current  
o Short-Circuit Current Foldback Protection  
o Thermal-Overload Protection

10% Power-OK (MAX8556)  
o 140ms Power-On Reset Output (MAX8557)  
o Fast Transient Response  
o 16-Pin Thin QFN (5mm x 5mm) Package  
The MAX8556/MAX8557 are available in a 16-pin thin  
QFN 5mm x 5mm package with exposed paddle.
