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 (>0.47µF). 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’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 TPS79733DCKT is a 3.3V fixed output low-dropout (LDO) Linear Regulator offers the benefits of 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. The device family low-dropout (LDO) and ultralow-powered operation results in a significant increase in system battery operating life. 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 The usual PNP pass transistor has been replaced by a PMOS pass element.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 PMOS pass element behaves as a low-value resistor, the dropout voltage is very low and is directly proportional to the load current. The quiescent current is ultralow and is stable over the entire range of output load current.
