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.
I
O
(Output Current) is the measured current when the output voltage drops 0.3 V with respect to V
O
at I
O
= 30 mA.
This measurement (pulse measurement) is with a constant T
J
. The output change due to temperature change is not included.
