9.5 POWER SUPPLY CHARACTERISTICS
The data was measured from a TLK100 evaluation board. The current from each of the power supply is
measured and the power dissipation is computed. For the single 3.3V external supply case the power dissipation
across the internal linear regulator is also included. All the power dissipation numbers are measured at the
nominal power supply and typical temperature of 25°C.
