The TPS734xx-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 44µA (typical) ground current. The TPS734xx-Q1 is stable with ceramic capacitors and uses an advanced BiCMOS fabrication process to yield a typical dropout voltage of 125mV at 250mA output. The TPS734xx-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 TA = –40°C to +105°C and is offered in a low-profile ThinSOT-23 package that are ideal for wireless handsets, printers, and WLAN cards.
