0.2V Dropout LDO Regulators  
General Description  
Features  
1.425V to 3.6V Input Voltage Range  
The MAX8516/MAX8517/MAX8518 low-dropout linear  
regulators operate from input voltages as low as 1.425V  
and are able to deliver up to 1A of continuous output cur-  
rent with a maximum dropout voltage of only 200mV. The  
Guaranteed 200mV Dropout at 1A Output Current  
±1.4% Output Accuracy Over Load, Line, and  
Temperature (0°C to +85°C), ±0.6% Initial Accuracy  
output voltage can be set from 0.5V to (V - 0.2V) and  
IN  
Compatible with Ceramic Capacitors  
● Fast Transient Response  
is 1.4% accurate over load and line variations, from 0°C  
to +85°C.  
These regulators use small, 1μF ceramic input capacitors  
and 4.7μF ceramic output capacitors to deliver 1A out-  
put current. High bandwidth provides excellent transient  
response and limits the output voltage deviation to 45mV  
for a 20mA to 1A load step, with only a 4.7μF ceramic out-  
put capacitor, and the voltage deviations can be reduced  
further by increasing the output capacitor.  
● 320μA Operating Supply Current  
● <25μA Shutdown Supply Current  
Short-Circuit Protection  
Thermal-Overload Protection  
Soft-Start Limits Inrush Current  
Ordering Information  
Designed with an internal p-channel MOSFET pass  
transistor, the MAX8516/MAX8517/MAX8518 feature low  
340μA (typ) supply current during dropout conditions.  
Soft-start reduces inrush current. Other features include  
a logic-controlled shutdown mode, short-circuit protection,  
and thermal-overload protection.
