Notes:
1. See thermal regulation specifications for changes in output voltage due to heating effects. Load and line regulation are
measured at a constant junction temperature by low duty cycle pulse testing.
2. Line and load regulation are guaranteed up to the maximum power dissipation. Power dissipation is determined by input/
output differential and the output current. Guaranteed maximum output power will not be available over the full input/output
voltage range.
3. Dropout voltage = VIN – VOUT when VOUT decreases to 98% of its nominal output voltage with VIN = VOUT + 1V. For output
voltages below 2.25V, dropout voltage is the input-to-output voltage differential with the minimum input voltage being 2.25V.
Minimum input operating voltage is 2.25V.
4. Flag output cannot be pulled to a voltage higher than VIN.
