3 Description
The TPS7A16A ultra-low-power, low-dropout (LDO)
voltage regulator offers the benefits of ultralow
quiescent current, high input voltage, and
miniaturized, high-thermal-performance packaging.
The TPS7A16A is designed for continuous or
sporadic (power backup) battery-powered applications
where ultra-low quiescent current is critical to
extending system battery life.
The TPS7A16A offers an enable pin (EN)
compatible with standard complementary metal oxide
semiconductor (CMOS) logic and an integrated opendrain,
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 TPS7A16A 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 wellregulated
voltage rail, but the TPS7A16A can also
withstand and maintain regulation during voltage
transients. These features translate to simpler
and more cost-effective, electrical surge-protection
circuitry.
