General Description  
Features  
The MAX8526/MAX8527/MAX8528 low-dropout linear  
regulators operate from input voltages as low as 1.425V  
and are able to deliver up to 2A of continuous output  
current with a maximum dropout voltage of only 200mV.  
o 1.425V to 3.6V Input Voltage Range  
o Guaranteed 200mV Dropout at 2A Output Current

Load/Lꢁne/Temperature (0°C to +85°C)  
o Compatꢁble wꢁth Ceramꢁꢂ Capaꢂꢁtors  
o Fast Transꢁent Response  
These regulators use small, 2.2µF ceramic input capaci-  
tors and 10µF ceramic output capacitors to deliver 2A  
output current. High bandwidth provides excellent tran-  
sient response and limits the output voltage deviation to  
45mV for a 20mA to 2A load step, with only a 10µF  
ceramic output capacitor, and the voltage deviations can  
be reduced further by increasing the output capacitor.  
o 440µA Operatꢁng Supplc Current  
o <50µA Shutdown Supplc Current  
o Short-Cꢁrꢂuꢁt Proteꢂtꢁon  
o Thermal-Oꢃerload Proteꢂtꢁon  
o Soft-Start Lꢁmꢁts Inrush Current  
o 5mm x 6.4mm Footprꢁnt, 1.1mm Profꢁle  
Designed with an internal p-channel MOSFET pass  
transistor, the MAX8526/MAX8527/MAX8528 feature  
low 500µA typical supply current during dropout condi-  
tions. Soft-start reduces inrush current. Other features  
include a logic-controlled shutdown mode, short-circuit  
protection, and thermal-overload protection.  
Ordering Information  
The MAX8527 features a power-OK (POK) output that  
transitions high when the regulator output is within  
10% of its nominal output voltage. The MAX8528 fea-  
tures a 150ms power-on reset (POR) output.
