May improve source impedance, noise, or PSRR. VOUT TPS799xx-Q1 EN GND NR 2.2m F Ceramic Optional bypass capacitor to reduce output noise and increase PSRR. 3 Description The TPS799xx-Q1 family of low-dropout (LDO) lowpower 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 Bi CMOS fabrication process to yield a dropout voltage of 100 m V (typical) at 200-m A 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.
