DESCRIPTION
The
TPS799xx
low-power
performance with very low ground current. High
power-supply rejection ratio (PSRR), low noise, fast
start-up,
and
excellent
response are provided while consuming a very low
40
μ
A (typical) ground current. The TPS799xx is
stable
with

capacitors
advanced
BiCMOS
fabrication
dropout voltage typically 100mV at 200mA output.
The TPS799xx uses a precision voltage reference
and feedback loop to achieve overall accuracy of 2%
over
all
load,
line,
process,
variations. It is fully specified from T
