5 / 17 page KA78LXXA/KA78L05AA 5 Electrical Characteristics(KA78L09A) (Continued) (VI = 15V, IO = 40mA, 0°C ≤ TJ ≤ 125°C, CI = 0.33μF, CO = 0.1μF, unless otherwise specified. (Note1) Note: 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 PD ≤ 0.75W. Parameter Symbol Conditions Min. Typ. Max.
