The external transistor is selected based on the required output current and collector saturation voltage. The
maximum collector saturation voltage is only important as the output voltage is close to the input voltage. This is
the case for a 3.3 V to 2.5 V conversion where the collector saturation voltage of the external transistor is lower
than 800 mV. To use low cost external transistors, the TPS65167 provides a minimum base drive current of 25
mA. The other important parameter is the maximum power dissipation the external transistor must be able to
handle. The power dissipation is the output current times the input to output voltage difference. See Table 14 for
the transistor selection
