ILIM  
For normal conditions this pin is connected to  
IN . When lower current is required, a resistor  
should be connected between ILIM and VIN.  
Limiting the switch current to 400 mA is  
achieved by connecting a 220 Ω resistor.

Input Voltage.  
SW1  
Collector of Power T ransistor. For step-down  
configuration, connect to VIN. For step-up  
configuration, connect to an inductor/diode.  
SO-8  
*N = Plastic DIP, SO = Small Outline Package.  
SW2  
Emitter of Power T ransistor. For step-down  
configuration, connect to inductor/diode. For  
step-up configuration, connect to ground. Do  
not allow this pin to go more than a diode  
drop below ground.  
GND  
AO  
Ground.  
Auxiliary Gain (GB) Output. T he open  
collector can sink 100 µA.  
SET  
Gain Amplifier Input. T he amplifier has  
positive input connected to SET pin and  
negative input connected to 1.245 V reference.  
FB/SENSE  
On the ADP1108 (adjustable) version this pin  
is connected to the comparator input. On the  
ADP1108-3.3, ADP1108-5 and ADP1108-12,  
the pin goes directly to the internal application  
resistor that set output voltage.  
CAUTIO N  
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily  
accumulate on the human body and test equipment and can discharge without detection.  
Although the ADP1108 features proprietary ESD protection circuitry, permanent damage may  
occur on devices subjected to high energy electrostatic discharges. T herefore, proper ESD  
precautions are recommended to avoid performance degradation or loss of functionality.
