500mA, Low Quiescent Current, Ultra-Low Noise, High PSRR
Low Dropout Linear Regulator
DESCRIPTION
The TPS735xx 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 46μA (typical) ground current. The TPS735xx is stable with ceramic capacitors and uses an advanced BiCMOS fabrication process to yield a typical dropout voltage of 250mV at 500mA output. The TPS735xx uses a precision voltage reference and feedback loop to achieve overall accuracy of 2% (VOUT > 2.2V) 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, 2mm x 2mm SON and 3mm × 3mm SON packages that are ideal for wireless handsets, printers, and WLAN cards.
