PIN DESCRIPTION
No connection.
PIN DESCRIPTIONS
The power input pin of the regulator. A minimum of input capacitance must be connected
from this pin to ground to insure that the input voltage does not sag below the minimum
dropout voltage during the load transient response. This pin must always be higher than
the V
OUT
pin by the amount of dropout voltage (see electrical specification) in order for the
device to regulate properly.
The output of the regulator. A minimum of output capacitance must be connected from
this pin to ground to insure stability.
This pin is connected with ground. It is also the tab of the package.

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:
Minimum load current is defined as the mini-
mum current required at the output in order for the out-
put voltage to maintain regulation.
Note 4:
Temperature stability is the change in output
from nominal over the operating temperature range.
Note 5:
Guaranteed by design, but not tested in produc-
tion.
