500mA Low-Dropout  
Linear Regulator in SOT23  
MAX18  
General Description  
Features  
The MAX1818 low-dropout linear regulator operates  
from a +2.5V to +5.5V supply and delivers a guaran-  
teed 500mA load current with low 120mV dropout. The  
high-accuracy ( 1ꢀ% output voltage is preset at an  
internally trimmed voltage (see Selector Guide% or can  
be adjusted from 1.25V to 5.0V with an external resis-  
tive divider.  
Guaranteed 500mA Output Current  
Low 120mV Dropout at 500mA  
1% Output Voltage Accuracy  
Preset at 1.5V, 1.8V, 2.0V, 2.5V, 3.3V, 5V  
Adjustable from 1.25V to 5.0V  
Power OK Output  
An internal PMOS pass transistor allows the low 125µA  
supply current to remain independent of load, making  
this device ideal for portable battery-operated equip-  
ment such as personal digital assistants (PDAs%, cellu-  
lar phones, cordless phones, base stations, and  
notebook computers.  
Other features include an active-low open-drain reset  
output that indicates when the output is out of regula-  
tion, a 0.1µA shutdown, short-circuit protection, and  
thermal shutdown protection. The device is available in  
a miniature 800mW 6-pin SOT23 package.
