ADP3330
APPLICATION CIRCUITS
Crossover Switch
The circuit in Figure 24 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 from the Ordering
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.
