DESCRIPTION
The TPS713xx family of low-dropout (LDO)
voltage regulators is tailored to noise-sensitive and RF applications. 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 regula...
