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
碌A(chǔ)
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.
