TPS799 is a 200mA, Low Quiescent Current, Ultra-Low Noise, High PSRR Low Dropout Linear Regulator

This post sponsored by Texas Instruments.

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. There is excellent load and line transient response. Multiple output voltage versions are available. 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 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.TPS799 is also suited for cellular phone, VCO, RF, handheld organizer, Bluetooth®, and PDA applications.
