Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

DescriptionThe TPS79718-Q1 family of low-dropout (LDO) voltage regulators offers the benefits of low-dropout voltage and ultralow-power operation. The TPS79718-Q1 is stable with any capacitor (>0.47 F). Therefore, implementations of this device require little board space due to the miniaturized packaging and potentially small output capacitor. In addition, the TPS79718-Q1 includes an integrated open drain active-high power good (PG) output.Intended for use in microcontroller based, battery-powered applications, the TPS79718-Q1 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 TPS79718-Q1 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 The usual PNP pass transistor has been replaced by a PMOS pass element.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 low, typically 105 mV at 10 mA of load current and is directly proportional to the load current. The quiescent current of TPS79718-Q1 is ultralow (1.2 A typically) and is stable over the entire range of output load current (0 mA to 10 mA). When properly configured with a pullup resistor, the PG output of TPS79718-Q1 can be used to implement a power-on reset or low battery indicator. The TPS797xx is offered in 1.8-V, 3-V,and 3.3-V fixed options.
