Electrical Characteristics
(Continued)
Note 3:
The maximum allowable power dissipation is a function of the maximum junction temperature, T
J(MAX)
, the junction-to-ambient thermal resistance,
θ
JA
, and
the ambient temperature, T
A
. The maximum allowable power dissipation at any ambient temperature is calculated using:
The value of
θ
for the SOT-23 package is 220C/W and the micro SMD package is 320C/W. Exceeding the maximum allowable power dissipation will cause ex-
cessive die temperature, and the regulator will go into thermal shutdown.
Note 4:
If used in a dual-supply system where the regulator load is returned to a negative supply, the LP2980 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
to V
OUT
will turn on this diode (see Application Hints).
Note 6:
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 Average Outgoing Quality Level (AOQL).
Note 7:
Dropout voltage is defined as the input to output differential at which the output voltage drops 100 mV below the value measured with a 1V differential.
Note 8:
The ON/OFF inputs must be properly driven to prevent misoperation. For details, refer to Application Hints.
Note 9:
See Typical Performance Characteristics curves.
Basic Application Circuit
DS012078-2
*
ON/OFF input must be actively terminated. Tie to V
IN
if this function is not to be used.
**
Minimum Output Capacitance is 1 μF to insure stability over full load current range. More capacitance provides superior dynamic performance and additional
stability margin (see Application Hints).

Do not make connections to this pin.
