TPS79718QDCKRQ1 is a linear voltage regulator with on-chip power switch control. It integrates 3 low groups of low-dropout (LDO) voltage regulators and 8 transient voltage suppressors (TVSs) to provide comprehensive protection for portable devices. It is designed for high performance requirements of the portable market such as smartphone and tablet applications. It can provide ultra-low quiescent current, excellent load transient response, high output voltage accuracy and fast response to power supply ripple.

The TPS79718QDCKRQ1 features a wide operating range in its input operating range, input voltage (VIN) ranging from +3V to +20V. It also features low output voltage accuracy (VOUT) of +1.2V to +3.3V. Its quiescent current is as low as 0.15mA, enabling the device to be used for very low power applications. The device also integrates a low-phase-noise PLL clock to reduce system noise.

The TPS79718QDCKRQ1 is designed for easy implementation and protection of portable consumer electronics. It has integrated protection mechanisms such as high temperature, short-circuit, ESD, reverse current, under-voltage lockout, reverse current, and overvoltage protection. This device also includes programmable foldback circuitry, which reduces current when the input voltage exceeds the specified limits, which can prevent system destruction due to abusive conditions.

The main function of the TPS79718QDCKRQ1 is to control the power switch by monitoring the input voltage. This allows the device to provide system power up when the input voltage is above the threshold. The device also has the ability to enable and disable the switching power supply, which can be adjusted by adjusting the enable pin.

The TPS79718QDCKRQ1 is ideal for mobile and portable applications where low quiescent power and tight load regulation are required. And by integrating the linear voltage regulator into the device, the TPS79718QDCKRQ1 achieves high power efficiency and low power dissipation. In addition, the device offers high ESD robustness, making it suitable for use in harsher environments.

Overall, the TPS79718QDCKRQ1 is a robust linear regulator suitable for many mobile and portable applications. Its wide range of input and output voltages, combined with its low quiescent current and excellent load transient response make it a great choice for low power and high efficiency applications.
