AIC1741  
LOW DROPOUT ADJUSTABLE REGULATOR  
SPEC NO: DS-1741-00  
FEATURES  
DESCRIPTION  
1% Accuracy 1.235V Voltage Reference.  
The AIC1741 is a low power precision adjustable  
regulator with 80mA output capability. The device  
can be used as a secondary regular to provide  
feedback in a switching power supply.  
Fast Transient Response.  
Low Ground Current at 55µA.  
Wide Output Current Range, 10µA~80mA.  
Output Programmable from 1.235V~11V.  
Low Temperature Coefficiency.  
Error Flag Warns of Output Dropout.  
The AIC1741 circuitry includes an internal wide  
band amplifier, a precision bandgap reference,  
and a PMOS output transistor. The feedback  
input can be connected to an external resistor  
divider to program the sensed output voltage.  
The VOUT pin provides loop frequency  
compensation when used as a part of a larger  
servo system.  
APPLICATIONS  
Voltage Regulator for Pentium® CPUs.  
Wireless Communication System.  
5V to 3.3V Regulator for VGA Cards.  
Battery Powered Systems.  
Although the device works as a stand-alone  
regulator, it can also drive an NPN power  
transistor to construct a high current low dropout  
regulator, with only very minor current loss to  
ground.
