TYPICAL APPLICATION CIRCUITS

The ADP5300 can be used as a keep-alive, ultralow power step-

down regulator to extend the 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 can achieve a quiet system

environment for a noise sensitive application.
