VIN = V OUT -NOM + 0.5 V or V IN = 1.6 V (whichever is higher), V EN = 1.2 V, I OUT = 1 mA, C IN = C OUT = 1.0 m F, T J = 25 ° C The specifications in bold are guaranteed at -40 ° C ≤ T J ≤ 85 ° C. (Note 4)

Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product performance may not be indicated by the Electrical Characteristics if operated under different conditions.

1. Performance guaranteed over the indicated operating temperature range by design and/or characterization. Production tested at T A = 25 ° C. Low duty cycle pulse techniques are used during the testing to maintain the junction temperature as close to ambient as possible.

2. Measured when the output voltage falls 3% below the nominal output voltage (the voltage measured under the condition V IN = V OUT -NOM + 0.5 V).
