3 Description
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 T_J = –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.
