Note 1:
Absolute maximum ratings indicate limits beyond which damage to the device may occur. Operating ratings indicate conditions for which the device is in-
tended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see Electrical characteristics. The guar-
anteed specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test
conditions.
Note 2:
At elevated temperatures, devices must be derated based on package thermal resistance. The device in the surface-mount package must be derated at
θ
jA
= 235C/W, junction-to-ambient. Please refer to the applications section on maximum current capability for further information. The device has internal thermal pro-
tection.
Note 3:
The human body model is a 100pF capacitor discharged through a 1.5k
resistor into each pin.
Note 4:
: Typical numbers are at 25C and represent the most likely parametric norm.
Note 5:
: Limits are 100% production tested at 25C. Limits over the operating temperature range are guaranteed through correlation using Statistical Quality Control
(SQC) methods. The limits are used to calculate National’s Averaging Outgoing Quality Level (AOQL).
Note 6:
If used in a dual-supply system where the regulator load is returned to a negative supply, the LP2966 output must be diode-clamped to ground.
Note 7:
The output PMOS structure contains a diode between the V
IN
and V
OUT
terminals that is normally reverse-biased. Reversing the polarity from V
IN
and V
OUT
will turn on this diode.
Note 8:
Output voltage line regulation is defined as the change in output voltage from the nominal value due to change in input line voltage.
Note 9:
Output voltage load regulation is defined as the change in output voltage from the nominal value when the load current changes from 1mA to 100mA.
Note 10:
Output voltage cross regulation is defined as the percentage change in the output voltage from the nominal value at one output when the load current
changes from 1mAto full load in the other output. This is an important parameter in multiple output regulators. The specification for
V
O1
/
I
OUT2
is equal to the speci-
fication for
V
O2
/
I
OUT1
.
Note 11:
Error Flag threshold and hysteresis are specified as the percentage below the regulated output voltage.
Note 12:
Dropout voltage is defined as the input to output differential at which the output voltage drops 100mV below the nominal value. Drop-out voltage specifi-
cation applies only to output voltages greater than 2.7V. For output voltages below 2.7V, the drop-out voltage is nothing but the input to output differential, since the
minimum input voltage is 2.7V.
Note 13:
Output voltage tolerance specification also includes the line regulation and load regulation.
