DESCRIPTION
The TPS799xx family of low-dropout (LDO)
low-power linear regulators offers excellent ac
performance with very low ground current. High
power-supply rejection ratio (PSRR), low noise, fast
start-up, and excellent line and load transient
response are provided while consuming a very low
40-μA (typical) ground current. The TPS799xx is
stable with ceramic capacitors and uses an advanced
BiCMOS fabrication process to yield a dropout
voltage of 100 mV (typ) at 200-mA output. The
TPS799xx uses a precision voltage reference and
feedback loop to achieve overall accuracy of 2% over
all load, line, process, and temperature variations. It
is fully specified from T_J = –40°C to 125°C and is
offered in low profile ThinSOT-23 and 2-mm × 2-mm
SON packages, ideal for wireless handsets and
WLAN cards.
