Notes:
1. The maximum steady state usable output current and input voltage are very dependent on the heat sinking and/or lead length
of the package. The data above represent pulse test conditions with junction temperature as indicated at the initiation of tests.
2. Power dissipation ≤ 0.75W.

Notes:
1. To specify an output voltage, substitute voltage value for “XX”.
2. Bypass Capacitors are recommend for optimum stability and transient response and should be located as close
as possible to the regulator
