3 Description
The TPS7A16xx-Q1 ultralow-power, low-dropout
(LDO) voltage regulators offer the benefits of ultralow
quiescent current, high input voltage, and
miniaturized, high-thermal-performance packaging.
The TPS7A16xx-Q1 devices are designed for
continuous or sporadic (power backup) battery-
powered applications where ultralow quiescent
current is critical to extending system battery life.
The TPS7A16xx-Q1 devices offer 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 TPS7A16xx-Q1 devices are ideal for
generating a low-voltage supply from multicell
solutions ranging from high-cell-count power-tool
packs to automotive applications; not only can these
devices supply a well-regulated voltage rail, but they
can also withstand and maintain regulation during
voltage transients. These features translate to simpler
and more cost-effective, electrical surge-protection
circuitry.
