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: Power dissipation<0.5W

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.
