SBVS189C –MARCH 2012–REVISED MAY 2012

1-A, Fast-Transient, Low-Dropout Voltage Regulator

FEATURES

DESCRIPTION

234

•

Low Dropout Voltage: 140 mV at 1A

V_INRange: 1.5 V to 6.5 V

The TPS7A7100 low-dropout (LDO) voltage regulator

is designed for applications seeking very-low dropout

capability (140 mv at 1A) with an input voltage from

1.5 V to 6.5 V. The TPS7A7100 offers an innovative,

user-configurable, output-voltage setting from 0.9 V to

3.5 V, eliminating external resistors and any

associated error.

•

Configurable Fixed V_OUTRange: 0.9 V to 3.5 V

Adjustable V_OUTRange: 0.9 V to 5.0 V

•

Very Good Load and Line Transient Response

Stable with Ceramic Output Capacitor

1.5% Accuracy over Line, Load, and

Temperature

The TPS7A7100 has very fast load-transient

response, is stable with ceramic output capacitors,

and supports a better than 2% accuracy over line,

load, and temperature. A soft-start pin allows for an

application to reduce inrush into the load.

Additionally, an open-drain, power-good signal allows

for sequencing power rails.

•

Programmable Softstart

Power Good (PG) Output

3-mm × 3-mm QFN-16 and 5-mm × 5-mm QFN-

20 Packages

The TPS7A7100 is available in a 3-mm × 3-mm,

16-pin QFN and a 5-mm × 5-mm, 20-pin QFN

packages.
