TYPICAL APPLICATION CIRCUITS

The ADP5302 can be used as a keep-alive, ultralow power step-

down regulator to extend battery life (see Figure 43) and as a

battery-powered equipment or wireless sensor network

controlled by a microcontroller or a processor (see Figure 44).

The stop switching function achieves a quiet system environment

for noise sensitive applications.
