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 44µA (typical) ground current. The TPS734xx is stable with ceramic capacitors and uses an advanced Bi CMOS fabrication process to yield a typical dropout voltage of 125m V at 250m A output. The TPS734xx 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, 2mm × 2mm SON, and 3mm x 3mm SON packages that are ideal for wireless handsets, printers, and WLAN cards.
