TPS71721DCKT

TPS71721DCKT is an adjustable and low-noise linear voltage regulator that provides excellent line and load regulation with low quiescent current & ESR. It is uniquely designed with low drop-out voltage and high PSRR to provide optimum power supply rejection performance over a wide input range. The small SOT-223 package is designated for power supply design which needs reliable and low noise performance.

The application field of TPS71721DCKT includes any DC linear voltage regulator needs, such as low drop-out voltage, low quiescent current, and low output noise. Typical application fields range from industrial, computing, networking, medical, automotive, consumer, and instrumentation applications.

The operating principle of TPS71721DCKT is straightforward. An external resistor at the EN pin sets the desired output voltage, and with typically <10uV of noise, the voltage regulator produces the desired output voltage.

The voltage regulator has a built-in error amplifier that compares the output voltage with a reference. It also monitors the feedback voltage at the FB pin to detect any shorted loads or excessive output currents, which would cause excessive heat dissipation.

The TPS71721DCKT features an adjustable operating frequency, which can be set with an external capacitor. This allows the voltage regulator to more efficiently manage heat dissipation and minimize wasted current.

The TPS71721DCKT also has a power good signal that indicates the status of the regulator output. This allows the system to detect any out-of-regulation conditions, protecting against overvoltage, undervoltage, or shorted load conditions.

Overall, the TPS71721DCKT is an excellent choice for any power supply application that requires reliable, low noise performance. It features a low drop-out voltage, low quiescent current, and power good signal that makes it a reliable and robust choice for any application.
