Electrical characteristics
V
IN
= V
O
= 0.5V, all values at T
A
= 25°C (Unless otherwise stated)
Device testing is performed at T
A
=25°C. Device thermal performance is guaranteed by design.
Note1: Maximum power dissipation is calculated assuming the device is mounted on a PCB measuring 2 inches square
Note2:Output voltage will start to rise when V
IN
exceeds a value or approximately 1.3V. For normal operation,
V
IN(min)
> V
OUT(nom)
+ 0.5V.
Note3:Dropout voltage is defined as the difference between V
IN
and V
O
, when V
O
has dropped 100mV below its nominal
value. Nominal value of V
O
is defined at V
IN
=V
O
+0.5V.
