TYPICAL APPLICATION CIRCUITS

The ADP5304 can be used as a keep-alive, ultralow power step-

down regulator to extend the battery life and load pulse current

capability with super capacitors (see Figure 28), and as a

battery-powered equipment or wireless sensor network

controlled by a microcontroller or a processor (see Figure 29).

The VINOK function can achieve the maximum power point

tracking.
