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.
