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 between V
IN
and V
OUT
required to maintain regu-
lation 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. Typically the resistor
dividers are selected such that it automatically main-
tains this current.
This pin is the positive side of the reference which allows remote load sensing to achieve
excellent load regulation.
When this pin is pulled lower than 1.4V with respect to the V
CTRL
pin the device is shut-
down. To enable the operation leave this pin open. Internal to device, there is a pull-up
resistor.
A resistor divider from this pin to the V
OUT
pin and ground sets the output voltage.
The output of the regulator. A minimum of 10
μ
F capacitor must be connected from this pin
to ground to insure stability.
This pin is the supply pin for the internal control circuitry as well as the base drive for the
pass transistor. This pin must always be higher than the V
OUT
pin in order for the device to
regulate. (See specifications)
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 higher than V
OUT
in
order for the device to regulate. (See specifications)
