TPS799-Q1 (ACTIVE)

200 mA, Low Quiescent Current, Ultra-Low Noise, High PSRR, LDO Linear Regulator for Automotive

200 mA, Low Quiescent Current, Ultra-Low Noise, High PSRR, LDO Linear Regulator for Automotive - TPS799-Q1
 

Description

The TPS799xx-Q1 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-Q1 is stable with ceramic capacitors and uses an advanced BiCMOS fabrication process to yield a dropout voltage of 100 mV (typical) at 200-mA output. The TPS799xx-Q1 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 thin SOT-23 and 2-mm × 2-mm SON packages, ideal for wireless handsets and WLAN cards.
