APPLICATION CIRCUITS
Crossover Switch
The circuit in Figure 24 shows that the ADP3303 and ADP3330
can be used to form a mixed supply voltage system. The output
switches between two different levels selected by an external
digital input. Output voltages can be any combination of
voltages from the Ordering Guide of the data sheet.

Higher Output Current
The ADP3330 can source up to 200 mA at room temperature
without any heatsink or pass transistor. If higher current is
needed, an appropriate pass transistor can be used, as in Figure
25, to increase the output current to 1 A.
