Note 1: All devices are 100% production tested at TJ = +25°C and +125°C. Limits at -40°C are guaranteed by design.
Note 2: Dropout voltage is defined as (VIN - VOUT) when VOUT is 98% of VOUT for VIN = 8V.
Note 3: Dropout voltage is defined as (VIN - VOUT) when VOUT is 98% of VOUT for VIN = 6V.
Note 4: Operation beyond the absolute maximum power dissipation is not guaranteed and may damage the part.
Note 5: Test at VIN = 8V (L/M), VIN = 6V (T/S), VIN = 5V (Z/Y/W/V).
