SBVS190B –MARCH 2012–REVISED APRIL 2012

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

FEATURES

DESCRIPTION

234

•

Low Dropout Voltage: 240 mV at 3A

V_INRange: 1.5 V to 6.5 V

The TPS7A7300 low-dropout (LDO) voltage regulator

is designed for applications seeking very-low dropout

capability (240 mV at 3A) with an input voltage from

1.5 V to 6.5 V. The TPS7A7300 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

2% Accuracy over Line, Load, and

Temperature

The TPS7A7300 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

5-mm × 5-mm QFN-20 Package
