PIN DESCRIPTIONS
PIN SYMBOL PIN DESCRIPTION
The input pin of the regulator. Typically a large storage capacitor is connected from this pin
to ground to insure that the input voltage does not sag below the minimum drop out voltage
during the load transient response. This pin must always be 0.6V higher than V
OUT
in order
for the device to regulate properly.
The output of the regulator. A minimum of 2.2
μ
F capacitor must be connected from this pin
to ground.
Ground pin. This pin must be connected to the lowest potential in the system and all other
pins must be at higher potential with respect to this pin.
Enable pin. A low signal or left open on this pin shuts down the output. This pin must be tied
HI or to V
IN
for normal operation.
An open collector output that switches low when the output voltage drops about 4% below
its expected regulated voltage.
A resistor divider from this pin to the V
OUT
pin and ground sets the output voltage.
APPLICATION INFORMATION
Stability
The
AP
U120X series of regulators require the use of an
output capacitor as part of the frequency compensation
in order to make the regulator stable. A minimum of 2.2
μ
F
capacitance and the ESR in the range of 0.5 to 2 in-
sures the stability of the system.

Table 1 - Output voltage vs. part number.
Note 1:
Low duty cycle pulse testing with Kelvin con-
nections is required in order to maintain accurate data.
Note 2:
Dropout voltage is defined as the minimum dif-
ferential voltage between V
IN
and V
OUT
required to main-
tain regulation at V
OUT
. It is measured when the output
voltage drops 1% below its nominal value.

Note 3
: Ground current is the regulator quiescent cur-
rent plus the pass transistor current. The total current
from the supply is the sum of the load current plus the
ground pin current.
Note 4

perature of 0 to +125
