ELECTRICAL CHARACTERISTICS −40

°C ≤ TJ ≤ 85°C; VBIAS = 2.7 V or (VOUT + 1.6 V), whichever is greater,

VIN = VOUT(NOM) + 0.3 V, IOUT = 1 mA, VEN = 1 V, CIN = 4.7 mF, COUT = 10 mF, CBIAS = 1 mF, unless otherwise noted.

Typical values are at TJ = +25°C. Min/Max values are for −40°C ≤ TJ ≤ 85°C unless otherwise noted. (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.

4. Performance guaranteed over the indicated operating temperature range by design and/or characterization. Production tested at TA = 25°C.

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

5. Dropout voltage is characterized when VOUT falls 3% below VOUT(NOM).

6. For fixed output voltages below 1.5 V, VBIAS dropout does not apply due to a minimum Bias operating voltage of 2.5 V.
