Texas Instruments TPS79933DDCR | Demoboard TIDA-00202

Description

The TPS799xx 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 TPS799xx is stable with ceramic capacitors and uses an advanced BiCMOS fabrication process to yield a dropout voltage of 100 mV (typ) at 200-mA 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 ThinSOT-23 and 2-mm × 2-mm SON packages, ideal for wireless handsets and WLAN cards.
