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.

Pin Functions
I/O
DESCRIPTION
I
Driving this pin high turns on the regulator. Driving this pin low puts the regulator into
shutdown mode. EN can be connected to IN if not used.
Ground
I
Input supply
Noise reduction; connecting this pin to an external capacitor bypasses noise generated by
the internal band gap. This capacitor allows output noise to be reduced to very low levels.
O
Output of the regulator. To assure stability, a small ceramic capacitor (total typical
capacitance 2.0 μF) is required from this pin to ground.
