5.2 Pin description

6. Functional description

[1] H = HIGH voltage level; L = LOW voltage level; X = don’t care; Z = high-impedance OFF-state.

7. Limiting values

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

[2] For SO20 package: above 70 °C the value of P

tot

derates linearly with 8.0 mW/K.

For TSSOP20 package: above 60 °C the value of P

tot

derates linearly with 5.5 mW/K.

For DHVQFN20 package: above 60 °C the value of P

tot

derates linearly with 4.5 mW/K.
