3 Description

The TPS7A7100 low-dropout (LDO) voltage regulator

is designed for applications requiring very-low dropout

capability (140 mV at 1 A) 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, thus eliminating external resistors and any

associated errors.

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.

The TPS7A7100 is available in 3-mm × 3-mm, 16-pin

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