[1]
Current from the 3.3 V supply will be mainly dependent on the external loads.
[2]
Current given is for optimum performance, lower current is possible with reduced performance.
[3]
Theta-JA (θJA) is the junction-to-ambient thermal resistance, when the package is mounted on a four-layer JEDEC
standard test board with no airflow and dissipating maximum power.
