4. Use pulse loading to limit power dissipation.
5. Dropout voltage = (VIN–VOUT), measured when the output voltage has dropped 100 mV relative to the nominal value obtained with
VIN = 13.5 V.
6. Not tested in production. Limits are guaranteed by design.
7. VDO = VIN -- VOUT. For output voltage set to < 4.5 V, VDO will be constrained by the minimum input voltage.
