Table 6. ELECTRICAL CHARACTERISTICS VIN = (VOUT + 1 V), VEN = VIN, IOUT = 1 mA, CIN = 10 mF, COUT = 10 mF, for typical
values TJ = 25°C, for Min/Max values TJ = −40°C to 125°C; unless otherwise noted. (Note 5) (continued)

5. Performance guaranteed over the indicated operating temperature range by design and/or characterization 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.
6. Maximum dropout voltage is limited by minimum input voltage. VIN = 1.7 V recommended for guaranteed operation at maximum output
current.
7. Refer to the Applications Information Section.
8. Values based on design and/or characterization.
9. Dropout voltage is defined as the differential voltage between VOUT and VIN, when VOUT drops 100 mV below its nominal value.
