SBVS056I – JANUARY 2005 – REVISED NOVEMBER 2007

The TPS799xx family of low-dropout (LDO) low-power linear regulators offer 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 µ A (typical) ground current. The TPS799xx is stable with ceramic capacitors and uses an advanced BiCMOS fabrication process to yield dropout voltage typically 100mV at 200mA output. The TPS799xx uses a precision voltage reference and feedback loop to achieve overall accuracy of 2% over all load, line, process, and temperature variations. It is fully specified from TJ= – 40 ° C to +125 ° C and is offered in low profile ThinSOT23, Wafer Chip-Scale (WCSP), and 2mm × 2mm SON packages, ideal for wireless handsets and WLAN cards.

APPLICATIONS

• Cellular Phones

• Wireless LAN, Bluetooth

• VCOs, RF

• Handheld Organizers, PDAs

SBVS056I – JANUARY 2005 – REVISED NOVEMBER 2007

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.

ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

Driving the enable pin (EN) high turns on the regulator. Driving this pin low puts the regulator into shutdown mode. EN can be connected to IN if not used.

Fixed voltage versions only; connecting an external capacitor to this pin bypasses noise low levels.

Adjustable version only; this pin is the input to the control loop error amplifier, and is used to set the output voltage of the device.

Output of the regulator. A small capacitor (total typical capacitance ≥ 2.0 µ F ceramic) is needed from this pin to ground to assure stability.
