3 Description

The TPS7A7200 low-dropout (LDO) voltage regulator

is designed for applications requiring very-low dropout

capability (180 mV at 2 A) with an input voltage from

1.5 V to 6.5 V. The TPS7A7200 offers an innovative,

user-configurable, output-voltage setting from 0.9 V

to 3.5 V, thus eliminating external resistors and any

associated errors.

The TPS7A7200 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.

The TPS7A7200 is available in 3-mm × 3-mm, 16-pin

VQFN and 5-mm × 5-mm, 20-pin VQFN packages.
