Functional description

[1]

H = HIGH voltage level;

L = LOW voltage level.

8.

Limiting values

[1]

The minimum input and output voltage ratings may be exceeded if the input and output current ratings are observed.

[2]

For SC-88 and SC-74 packages: above 87.5

°C the value of P

tot derates linearly with 4.0 mW/K.
