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. These devices 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 the measured output. Each regulator output is stable with low-cost 2.2 μF ceramic output capacitors and features very low dropout voltages (125 mV typical at 250 mA). Each regulator achieves fast start-up times (approximately 60 μs with a 0.001 μF bypass capacitor) while consuming very low quiescent current (300 μA typical with both outputs enabled).
