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.
