Electrical Characteristics (MC78L05A / LM78L05A)

VI = 10 V, IO = 40 mA, 0°C ≤ TJ ≤ 125°C, CI = 0.33 μF, CO = 0.1 μF, unless otherwise specified.

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 represents pulse test conditions with junction temperature as indicated

at the initiation of tests.

2. Power dissipation PD ≤ 0.75 W.
