8.1 Application Information
The TPS7A16 family of ultralow power voltage regulators offers the benefit of ultralow quiescent current, high
input voltage, and miniaturized, high thermal-performance packaging.
The TPS7A16 family is designed for continuous or sporadic (power backup) battery-operated applications where
ultralow quiescent current is critical to extending system battery life.
