TPS71334

The TPS713xx family of low-dropout (LDO) voltage regulators is tailored to noise-sensitive and RF appli cations. These products feature dual 250 mA LDOs with ultralow noise, high power-supply rejection ratio (PSRR), and fast transient and start-up response. TPS713xx also feature an integrated supply voltage supervisor (SVS) that monitors the voltage at OUT2 and will assert if the voltage falls to 95% (typical) of thd measured output.Each regulator output is stable with low-cost 2.2F ceramic output capacitors and features very low dropout voltages (125 mV typical at 250 mA). Each regulator achieves fast start-up times (approximately 60 s with a 0.001 F bypass capacitor) while consuming very low quiescent current (300 A typical with both outputs enabled). When the TPS713xx is placed in standby mode, the supply current is reduced to less than 0.3 A typical. Each regulator exhibits approximately 32Vrms of output voltage noise with VOUT=2.8V ang a 0.01F noise reduction (NR) capacitor.Applications wisth analog components that are noise-sensitive,such as portable RF electronics,will benefit from high PSRR,low noise,and fast line and load transient features. The TPS713xx family is offered in a thin 3mm x 3mm SON package and is fully specified from -40°C to +125°C (TJ).
