DEFINITION AND EXPLANATION OF TECHNICAL TERMS
OUTPUT VOLTAGE (V
O
)
The output voltage is specified with V
IN
= (V
O(TYP)
+ 1 V)
and I
O
= 30 mA.
DROPOUT VOLTAGE (V
DROP
)
The dropout voltage is the difference between the input
voltage and the output voltage at which point the regulator
starts to fall out of regulation. Below this value, the output
voltage will fall as the input voltage is reduced. It is
dependent upon the load current and the junction tempera-
ture.
OUTPUT CURRENT (I
O
MAX)
The rated output current is specified under the condition
where the output voltage drops 0.3 V below the value
specified with I
O
= 30 mA. The input voltage is set to V
O
+1
V, and the current is pulsed to minimize temperature effect.
CONTINUOUS OUTPUT CURRENT (I
O
)
Normal operated output current. This is limited by package
power dissipation.
PULSE OUTPUT CURRENT (I
O (PULSE)
)
Max pulsewidth 5ms, Duty cycle 12.5%: pulse load only
LINE REGULATION (LINE REG)
Line Regulation is the ability of the regulator to maintain a
constant output voltage as the input voltage changes. The
line regulation is specified as the input voltage is changed
from V
IN
= V
O
+ 1V to V
IN
= V
O
+ 6V.
LOAD REGULATION (LOAD REG)
Load regulation is the ability of the regulator to maintain a
constant output voltage as the load current changes. It is
a pulsed measurement to minimize temperature effects
with the input voltage set to V
IN
= V
O
+1 V. The load
regulation is specified under two output current step condi-
tions of 1 mA to 60 mA and 1 mA to 100 mA.
QUIESCENT CURRENT (IQ)
The quiescent current is the current which flows through
the ground terminal under no load conditions (I
O
= 0 mA)
RIPPLE REJECTION RATIO
Ripple rejection is the ability of the regulator to attenuate
the ripple content of the input voltage at the output. It is
specified with 100 mVrms, 400 Hz superimposed on the
input voltage, where V
IN
= V
O
+ 1.5 V. The output decoupling
capacitor is set to 10
μ
F, the noise bypass capacitor is set
to 0.1
μ
F, and the load current is set to 30 mA. Ripple
rejection is the ratio of the ripple content of the output vs. the
input and is expressed in dB.
STANDBY CURRENT
Standby current is the current which flows into the regulator
when the output is turned off by the control function (V
CONT
= V
IN
.) It is measured with V
IN
= 8 V (9 V for the 8 V output
device.)
SENSOR CIRCUIT
Over current sensor
The overcurrent sensor protects the device in the event
that the output is shorted to ground.
Thermal sensor
The thermal sensor protects the device in the event
that the junction temperature exceeds the safe value
(T
J
= 150
°
C). This temperature rise can be caused by
external heat, excessive power dissipation caused by
large input to output voltage drops, or excessive output
current. The regulator will shut off when the tempera-
ture exceeds the safe value. As the junction tempera-
tures decrease, the regulator will begin to operate
again. Under sustained fault conditions, the regulator
output will oscillate as the device turns off then resets.
Damage may occur to the device under extreme fault
conditions.
Reverse Voltage Protection
Reverse voltage protection prevents damage due to
the output voltage being higher than the input voltage.
This fault condition can occur when the output capaci-
tor remains charged and the input is reduced to zero,
or when an external voltage higher than the input
voltage is applied to the output side.
