TPS79920YZUR Low-Quiescent Current, Ultralow Noise, High-PSRR Low-Dropout Linear Regulator BGA spot stock

Product Descriptions

The  TPS799  low-dropout  (LDO),  low-power  linear regulator  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  TPS799  is  stable with  ceramic  capacitors  and uses  an  advanced  BiCMOS  fabrication  process  to yield a dropout voltage of typically 100 mV at a 200-mA  output.  The  TPS799  uses  a  precision  voltage reference  and  feedback  loop  to  achieve  an  overall accuracy  of  2%  over  all  load,  line,  process,  and temperature variations. The TPS799 features inrush current protection when the EN toggle is used to start the device, immediately clamping the current.

This  device  is  fully  specified  over  the  temperature range  of  TJ   =  –40°C  to  +125°C,  and  is  offered in  a  low-profile,  die-sized  ball  grid  array  (DSBGA) package,   making  this  device  a  good  choice  for wireless  handsets and WLAN cards. This device  is also offered in 5-pin SOT-23-THIN and 6-pin WSON packages.
