DESCRIPTION
The TPS797xx family of low-dropout (LDO)
voltage regulators offers the benefits of low-dropout
voltage and ultralow-power operation. The device is stable with any capacitor (>0.47 µF). Therefore, implementations of this device require 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’s 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. The usual PNP pass transistor has been replaced by a PMOS pass element. Because the P...
