1. Derate 20mW/ºC above 25°C ambient temperature. Stresses above those listed in Absolute Maximum Ratings may cause permanent damage to the device. Functional opera-
tion at conditions other than the operating conditions specified is not implied.
2. Mounted on an FR4 board.
3. To calculate minimum input voltage, use the following equation: VIN(MIN) = VOUT(MAX) + VDO(MAX) as long as VIN ≥ 2.5V.
