These products feature dual 250 mA LDOs Monitors VOUT2 with ultralow noise, high power-supply rejection ratio • Available in Fixed and Adjustable (PSRR), and fast transient and start-up response. Voltage Options (1.2 V to 5.5 V) These devices also feature an integrated supply • High PSRR: 65 dB at 10 kHz voltage supervisor (SVS) that monitors the voltage at OUT2 and will assert if the voltage falls to 95% • UltraLow Noise: 32 µVrms (typical) of the measured output. Each regulator • Fast Start-Up Time: 60 µs output is stable with low-cost 2.2 µF ceramic output • Stable with 2.2 µF Ceramic Capacitor capacitors and features very low dropout voltages (125 mV typical at 250 mA). Each regulator achieves • Excellent Load/Line Transient Response fast start-up times (approximately 60 µs with a • Very Low Dropout Voltage: 125 mV at 250 mA 0.001 µF bypass capacitor) while consuming very low • Independent Enable Pins quiescent current (300 µA typical with both outputs enabled). When the device is placed in standby • Thermal Shutdown and Independent Current mode, the supply current is reduced to less than Limit 0.3 µA typical. Each regulator exhibits approximately • Available in Thermally-Enhanced SON 32 µVrms of output voltage noise with VOUT = 2.8 V Package: 3mm x 3mm x 1mm and a 0.01 µF noise reduction (NR) capacitor. Appli- cations with analog components that are noise-sensitive, such as portable RF electronics, will • Cellular and Cordless Phones benefit from high PSRR, low noise, and fast line and load transient features. The TPS713xx family is • Wireless PDA/Handheld Products offered in a thin 3mm x 3mm SON package and is • PCMCIA/Wireless LAN Applications fully specified from -40 °C to +125°C (T J). • Digital Camera/Camcorder/Internet Audio • DSP/FPGA/ASIC/Controllers and Processors 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.
