PIN DESCRIPTION
PIN DESCRIPTIONS
The control input pin of the regulator. This pin is connected to the 5V supply to provide
base current for the pass transistor of the regulator. This allows the regulator to have very
low dropout voltage, enabling use with low values of VIN. A 1
mF high frequency capacitor
is connected from this pin to VIN to ensure stability.
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 VOUT pin by the amount of dropout voltage (see data sheet) in order for the device to
regulate properly.
This pin is connected with ground. It is also the tab of the package.
The output of the regulator. A minimum of output capacitance must be connected from
this pin to ground to insure stability.
A resistor divider from this pin to the VOUT pin and to ground sets the output voltage. See
application section for divider setting recommendations and a circuit example.

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 VIN and VOUT required to main-
tain regulation at VOUT. 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.
