2. Performance guaranteed over the operating temperature range by design and/or characterization, production tested at TJ = TA = 25C. Low

duty cycle pulse techniques are used during testing to maintain the junction temperature as close to ambient as possible.

3. TA must be greater than 0C.

4. Maximum dropout voltage is limited by minimum input voltage Vin = 2.9 V recommended for guaranteed operation.
