description
The TPS708xx is a low-dropout voltage regulator
with integrated SVS (RESET, POR, or power on
reset) and power good (PG) functions. These
devices are capable of supplying 250 mA and 125
mA by regulator 1 and regulator 2 respectively.
Quiescent current is typically 190
A at full load.
Differentiated features, such as accuracy, fast
transient response, SVS supervisory circuit
(power on reset), manual reset input, and
independent enable functions provide a complete
system solution.
