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 represent 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 " XXM".

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

as close as possible to the regulators.
