3. Use pulse loading to limit power dissipation.

4. Dropout voltage = (VIN – VOUT), measured when the output voltage has dropped 100 mV relative to the nominal value obtained with

VIN = 13.5 V.

5. Not tested in production. Limits are guaranteed by design.

6. VDO = VIN - VOUT. For output voltage set to < 4.5 V, VDO will be constrained by the minimum input voltage.
