ADP3330

APPLICATION CIRCUITS

CROSSOVER SWITCH

The circuit in Figure 27 shows how two ADP3330s 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 that

are included in the Ordering Guide.

Figure 27. Crossover Switch

HIGHER OUTPUT CURRENT

The ADP3330 can source up to 200 mA at room temperature

without any heat-sink, or pass transistor. If higher current is

needed, an appropriate pass transistor can be used, as in

Figure 28, to increase the output current to 1 A.
