Note 1: The Maximum steady state usable output current are dependent on input voltage, heat sinking, lead length

of the package and copper pattern of PCB. The data above represents pulse test conditions with junction

temperatures specified at the initiation of test.

Note 2:

Note 1: To specify an output voltage, substitute voltage value for "XX".

Note 2: Bypass capacitors are recommended for optimum stability and transient response and should be located as

close as possible to the regulators.
