TPS79918DDCR

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.
