_______________________________________________________________________________________
Note 2: All devices are 100% production tested at +25°C and are guaranteed by correlation for TA = TMIN to TMAX.
Note 3: Guaranteed by design.
Note 4: Dropout voltage is defined as (VIN - VOUT) when VOUT is 2% below the value of VOUT for VIN = VOUT(NOM) + 1V.
Note 5: MAX6473/MAX6474/MAX6481/MAX6482 are guaranteed by design for VOUT < 2.5V.
Note 6: Select the reset timeout period using the Reset Timeout Delay Guide (Table 3). Insert the appropriate suffix in the part number
when ordering.
ELECTRICAL CHARACTERISTICS (continued)
(VIN = (VOUT + 0.5V) or +2.5V, whichever is greater, COUT = 3.3F, TA = -40°C to +85°C. Typical specifications are at TA = +25°C,
unless otherwise noted.) (Note 2)
