3 Description

The TPS7A16 family of ultralow power, low-dropout (LDO) voltage regulators offers the benefits of ultra-low quiescent current, high input voltage and miniaturized, high thermal-performance packaging.

The TPS7A16 family is designed for continuous or sporadic (power backup) battery-powered applications where ultralow quiescent current is critical to extending system battery life.

The TPS7A16 family offers an enable pin (EN) compatible with standard CMOS logic and an integrated open drain active-high power good output (PG) with a user-programmable delay. These pins are intended for use in microcontroller-based, battery-powered applications where power-rail sequencing is required.

In addition, the TPS7A16 is ideal for generating a low-voltage supply from multicell solutions ranging from high cell-count power-tool packs to automotive applications; not only can this device supply a well-regulated voltage rail, but it can also withstand and maintain regulation during voltage transients. These features translate to simpler and more cost-effective, electrical surge-protection circuitry.
