Note 1:

Note 3:

Note 4:

Power dissipation must be derated at rate of 1.6 mW/°C for operation above 25 °C. Maximum power dissipation = 400 mW

(When mounted as recommended), and 200 mW in free air.

Output side capacitor should have low ESR at low temperatures if used below 0 °C.

IO (Output Current) is the measured current when the output voltage drops 0.3 V with respect to VO at IO = 30 mA.

This measurement (pulse measurement) is with a constant TJ. The output change due to temperature change is not included.
