Electrical Characteristics
Limits in standard typeface are for T
less otherwise specified: V
Note 1: Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical specifications do not apply when operating the
device outside of its rated operating conditions.
Note 2: The ESD rating of pins 3 and 4 for the SOT-23 package, or pins 5 and 2 for the micro SMD package, is 1 kV.
Note 3: The maximum allowable power dissipation is a function of the maximum junction temperature, T
the ambient temperature, T
The value of θ
excessive 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 LP2982 output must be diode-clamped to ground.
Note 5: The output PNP structure contains a diode between the V
will turn on this diode.
Note 6: 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 possible misoperation. For details, refer to Application Hints.
Note 9: See Typical Performance Characteristics curves.
Note 10: Exposing the micro SMD device to direct sunlight will cause misoperation. See Application Hints for additional information.
