DESCRIPTION
The TPS799xx family of low-dropout (LDO)
low-power linear regulators offer excellent AC per-
formance with very low ground current. High
power-supply rejection ratio (PSRR), low noise, fast
start-up, and excellent line and load transient re-
sponse are provided while consuming a very low
40碌A(chǔ) (typical) ground current. The TPS799xx is
stable with ceramic capacitors and uses an advanced
BiCMOS fabrication process to yield dropout voltage
typically 110mV at 200mA 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 speci-
fied from T
J
= -40擄C to +125擄C and is offered in low
profile ThinSOT23 and Wafer Chip-Scale packages
(WCSP), ideal for wireless handsets and WLAN
cards.
