The TPS799 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 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.
All devices are fully specified over the temperature range of TJ =
–40°C to 125°C, and offered in a low-profile, die-sized ball grid array (DSBGA) package, ideal for
wireless handsets and WLAN cards.
