Note 1: Parts are 100% tested at +25°C. Limits across the full temperature range are guaranteed by design and correlation over the
specified temperature range.
Note 2: The dropout voltage is measured from VIN to VOUT when VOUT is 2% below its nominal value. The nominal output voltage is
measured from VOUT to GND when VIN is 1V greater than VOUT. Defined only for VOUT
≥ 2.5V.
Note 3: Soft-start time is defined as the time required for the output to rise from 10% of its nominal value to 90% of its nominal value.
Note 4: For VOUT < 2V, VIN must be above 2.5V.
Note 5: This is the maximum time OUT can be out of tolerance before a reset is issued. It is implemented to ensure that momentary
output glitches do not trigger a reset condition.
Note 6: In startup mode, the blanking time counter is not started until the soft-start time has elapsed. The total time from startup to
FLAG issued is tSS + tBLANK.
ELECTRICAL CHARACTERISTICS (continued)
(VIN = VOUT + 1V, SHDN = IN, COUT = 3.3F, TA = -40°C to +85°C, unless otherwise noted. Typical values are at TA = +25°C.) (Note 1)
