H = HIGH voltage level; L = LOW voltage level; X = don’t care; Z = high-impedance OFF-state.
The minimum input and output voltage ratings may be exceeded if the input and output current ratings are observed.
For SO20 package: above 70 C the value of P
For TSSOP20 package: above 60 C the value of P
For DHVQFN20 package: above 60 C the value of P
