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

Ω resistor into each pin.

Note 3: The maximum allowable power dissipation is calculated by using PDMAX =(TJMAX -TA/θJA, where TJMAX is the maximum junction temperature, TA is the

ambient temperature, and

θJA 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 TJMAX, θJA 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 VIN and VOUT terminals that is normally reverse-biased. Reversing the polarity from VIN and VOUT

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.
