Note 1:
Absolute maximum ratings indicate limits beyond which damage to the device may occur. Electrical specifications do not apply when operating the device
beyond its rated operating conditions.
Note 2:
Rating is for the human body mode, a 100pF capacitor discharged through a 1.5k
resistor into each pin.
Note 3:
The maximum allowable power dissipation is calculated by using P
DMAX
= (T
JMAX
- T
A
/
θ
JA
, where T
JMAX
is the maximum junction temperature, T
A
is the
ambient temperature, and
θ
JA
is the junction-to-ambient thermal resistance of the specified package. Therefore, the maximum power dissipation must be derated
at elevated temperatures and is limited by T
JMAX
,
θ
JA
and
A
.
Note 4:
If used in a dual-supply system where the regulator load is returned to a negative supply, the LP2967 output must be diode-clamped to ground.
Note 5:
The output PNP 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 6:
Load regulation excursion over temperature is included in Output Voltage Tolerance.
Note 7:
The dropout voltage of a regulator is defined as the minimum input-to-output differential required to stay within 100mV of the output voltage measured with
a 1V differential.
