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.
