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:
Transient response is defined with a step change
in load from 10mA to I
FL
/2, as the time from the load step
until the output voltage reaches its minimum value.
Note 4:
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 5:
The regulator shall withstand 100,000 reverse
bias discharges of the maximum output capacitance,
with no degradation, when the input voltage is switched
to ground in 1
μ
s.
Note 6:
Temperature stability is the change in output
from nominal over the operating temperature range.
Note 7:
Guaranteed by design, but not tested in produc-
tion.

pins by the amount of the dropout voltage in order for the device to regulate
properly. Bypass to ground with low ESR and ESL capacitance.
Output #3. Fixed regulator output (8V).
Input voltage to supply the base current for the pass transistor for both regulators.
