PIN DESCRIPTION
Mnemonic
I
LIM
Function
For normal conditions this pin is connected to
V
IN
. When lower current is required, a resistor
should be connected between I
LIM
and V
IN
.
Limiting the switch current to 400 mA is
achieved by connecting a 220
resistor.
Input Voltage.
Collector Node of Power Transistor. For step-
down configuration, connect to V
IN
. For step-
up configuration, connect to an inductor/diode.
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.
Ground.
Auxiliary Gain (GB) Output. The open collec-
tor can sink 300
μ
A. It can be left open if unused.
Gain Amplifier Input. The amplifier has posi-
tive input connected to SET pin and negative
input connected to 220 mV reference. It can be
left open if unused.
On the ADP1110 (adjustable) version this pin
is connected to the comparator input. On the
ADP1110-3.3, ADP1110-5 and ADP1110-12,
the pin goes directly to the internal application
resistor that set output voltage.

WARNING!
ESD SENSITIVE DEVICE
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 ADP1110 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.
