DESCRIPTION
The TPS734xx 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
44mA (typical) ground current. The TPS734xx 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
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 ThinSOT-23, 2mm × 2mm SON, and 3mm
x 3mm SON packages that are ideal for wireless
handsets, printers, and WLAN cards.
