The TPS719xx also provides an active pulldown • Independent Enables for Each LDO circuit to quickly discharge output loads. The • PSRR: 65dB at 1kHz, 45dB at 1MHz TPS718xx and TPS719xx are stable with ceramic • Available in Multiple Fixed-Output Voltage capacitors and use an advanced BiCMOS fabrication Combinations from 0.9V to 3.6V Using process to yield a typical dropout voltage of 230mV Innovative Factory EEPROM Programming at 200mA output loads. The TPS718xx and TPS719xx also use a precision voltage reference • Fast Start-Up Time: 160µs and feedback loop to achieve 3% overall accuracy • Over-Current, Over-Temperature and over all load, line, process, and temperature Under-Voltage Protection variations. Both families of devices are fully specified • Low Dropout: 230mV at 200mA from TJ = –40°C to +125°C and are offered in a 2mm × 2mm SON-6 package that is ideal for applications • Stable with 1µF Ceramic Output Capacitor such as mobile handsets and WLAN that require • Available in 2mm × 2mm SON-6 Package good thermal dissipation while maintaining a very small footprint. • Digital Cameras • Cellular Camera Phones • Wireless LAN, Bluetooth® • Handheld Products Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
