REV. 0
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.

PIN DESCRIPTIONS
Mnemonic
Function
I
LIM
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 collector
can sink 300
μ
A. It can be left open if unused.
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.
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.
