(1) Pulse-testing techniques maintain the junction temperature as close to the ambient temperature as possible. Thermal effects must be
taken into account separately. All characteristics are measured with a 0.33-μF capacitor across the input and a 0.1-μF capacitor across
the output.
(2) This parameter is validated by design and verified during product characterization. It is not tested in production.
