NOTE:

1. Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating

Conditions are conditions under which the device functions but the specifications might not be

guaranteed. For guaranteed specifications and test conditions see the Electrical Characteristics.

2. The maximum power dissipation is a function of the maximum junction temperature, TJmax ; total

thermal resistance, JA, and ambient temperature TA. The maximum allowable power dissipation at

any ambient temperature is Tjmax-TA / JA. If this dissipation is exceeded, the die temperature will

rise above 150°C and IC go into thermal shutdown. The JA of SOT-223 package is 147°C/W (See

Recommended Minimum Footprint).

3. Low duty pulse techniques are used during test to maintain junction temperature as close to ambient

as possible.

The type of output capacitor should be tantalum or aluminum.
