Mnemonic  
ILIM  
For normal conditions this pin is connected to  
VIN. 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 resistor.  
VIN  
Input Voltage.  
SW1  
Collector Node of Power Transistor. For step-  
down configuration, connect to VIN. For step-up  
configuration, connect to an inductor/diode.  
TYPICAL APPLICATION  
SW2  
Emitter Node of Power Transistor. 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.

SET  
Gain Amplifier Input. The amplifier’s positive  
input is connected to SET pin and its negative  
input is connected to the 1.25 V reference. It can  
be left open if unused.  
GND SW2  
FB/SENSE  
On the ADP1111 (adjustable) version this pin  
is connected to the comparator input. On the  
ADP1111-3.3, ADP1111-5 and ADP1111-12,  
the pin goes directly to the internal application  
resistor that sets output voltage.

CAUTION  
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 ADP1111 features proprietary ESD protection circuitry, permanent damage may  
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD  
precautions are recommended to avoid performance degradation or loss of functionality.  
WARNING!
