(1)

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings

only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended

Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(2)

If Military/Aerospace-specified devices are required, contact the Texas Instruments Sales Office/Distributors for availability and

specifications.

(3)

The maximum allowable power dissipation is a function of the maximum junction temperature, TJ(MAX), the junction-to-ambient thermal

resistance, RθJA, and the ambient temperature, TA. The maximum allowable power dissipation at any ambient temperature is calculated

using P(MAX) = (TJ(MAX) – TA) / RθJA. The value of RθJA for the SOT-23 package is 169°C/W. Exceeding the maximum allowable power

dissipation causes excessive die temperature, and the regulator will go into thermal shutdown.

(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.

(5)

The output PNP structure contains a diode between the IN and OUT pins that is normally reverse-biased. Reversing the polarity from

VIN to VOUT turns on this diode (see Reverse Current Path).
