DESCRIPTION  
•
200-mA Low-Dropout (LDO) Regulator  
With Enable (EN)  
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 TJ = –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.
