4. Performance guaranteed over the indicated 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.

5. Characterized when VOUT falls 100 mV below the regulated voltage at VIN = VOUT(NOM) + 0.3 V.
