DESCRIPTION
The TPS799xx family of low-dropout (LDO)
low-power linear regulators offer 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
40µA (typical) ground current. The TPS799xx is
stable with ceramic capacitors and uses an advanced
BiCMOS fabrication process to yield 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, and temperature variations. It is fully
specified from T_J = –40°C to +125°C and is offered in
low profile ThinSOT23, Wafer Chip-Scale (WCSP),
and 2mm × 2mm SON packages, ideal for wireless
handsets and WLAN cards.
