Electrical Characteristics (Continued)

The value of

θJA for the SOT-23 package is 220˚C/W. Exceeding the maximum allowable power dissipation will cause 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 LP2980LV output must be diode-clamped to ground.

Note 5: The output PNP structure contains a diode between the VIN and VOUT terminals that is normally reverse-biased. Reversing the polarity from VIN to VOUT

will turn on this diode and possibly damage the device (see Application Hints).

Note 6: Limits are 100% production tested at 25˚C. 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: The ON/OFF input must be properly driven to prevent misoperation. For details, refer to Application Hints.

Note 8: See Typical Performance Characteristics curves.
