TI’s new TPS719xx LDOs feature an active shutdown circuit to quickly discharge capacitors at the output voltage. Discharging the capacitors to zero during shutdown helps to manage power-up when
sequencing applications. The TPS719xx devices are stable with ultra-small 1-µF ceramic capacitors, and leverage an advanced linear Bi-CMOS process technology to yield a typical dropout voltage of 230-mV
at 200-mA output loads. The LDOs also use a precision voltage reference and feedback loop to achieve a three percent overall accuracy over all load, line, process and temperature variations.
The devices come in a 6-pin, 2 mm x 2 mm, SON package, which is targeted at portable applications, such as mobile handsets, digital still cameras and wireless LAN applications that require good thermal
dissipation, while maintaining a small footprint.
The TPS719xx family of LDOs is available today in volume from TI and its authorized distributors. Suggested retail pricing in 1,000-piece quantities is $0.75.
