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.
4. Effective capacitance, including the effect of DC bias, tolerance and temperature. See the Application Information section for more
information.
5. 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.
6. Dropout voltage is characterized when V
OUT
falls 3% below V
OUT(NOM)
.
7. For output voltages below 0.9 V, V
BIAS
dropout voltage does not apply due to a minimum Bias operating voltage of 2.4 V.
