    Description

    The TPS797xx family of low-dropout (LDO) voltageregulators offers the benefits of low-dropout voltage and ultralow-power operation. The device is stable with any capacitor (> 0.47µF). Therefore, implementations of this device require very little board space due to the miniaturized packaging and potentially small output capacitor. In addition, the family includes an integrated open drain active-high power good (PG) output. Intended for use in microcontroller-based, battery-powered applications, the TPS797xx family low dropout and ultralow-powered operation results in a significant increase in system battery operating life. The small packaging minimizes consumption of board space.

    The device is enabled when the applied voltage exceeds the minimum input voltage.
