The TPS799-Q1 low-dropout (LDO) low-power linear regulator 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-Q1 is stable with ceramic capacitors and uses an advanced BiCMOS fabrication process to yield a dropout voltage of 100 mV (typical) at a 200-mA output. The TPS799-Q1 uses a precision voltage reference and feedback loop to achieve overall accuracy of 2% over all load, line, process, and temperature variations. The device is fully specified from T J = –40°C to +125°C and is offered in low-profile, thin SOT-23 and 2-mm × 2-mm WSON packages, designed for wireless handsets and WLAN cards.
