3 Description

The TPS799L 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 TPS799Lxx 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 TPS799L uses a precision

voltage reference and feedback loop to achieve an

overall accuracy of 2% over all load, line, process,

and temperature variations. The TPS799L 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.
