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.
