(1)

Stresses beyond those listed under

"absolute maximum ratings" may cause permanent damage to the device. These are stress ratings

only, and functional operation of the device at these or any other conditions beyond those indicated under

"recommended operating

conditions

" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(2)

Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient

temperature is PD = (TJ(max) – TA)/θJA. Operating at the absolute maximum TJ of 150°C can affect reliability.

(3)

The package thermal impedance is calculated in accordance with JESD 51-7.

(4)

The package thermal impedance is calculated in accordance with JESD 51-5.

≤ rated dissipation

(1)

Unless otherwise noted, these specifications apply for the following test conditions: VI – VO = 5 V and IO = 40 mA. Pulse-testing

techniques must be used that maintain the junction temperature as close to the ambient temperature as possible. All characteristics are

measured with a 0.1-

μF capacitor across the input and a 1-μF capacitor across the output.

(2)

Input voltage regulation is expressed here as the percentage change in output voltage per 1-V change at the input.
