Introduction to the TPS76918DBVR

The TPS76918DBVR is a low dropout linear voltage regulator that provides excellent power supply regulation and stable output current. It can regulate a wide range of voltage levels and is capable of driving up to 1A of output current. The device features built-in protection features that make it ideal for use in applications such as industrial, automotive, consumer and environmental sensing.

Application Fields

The TPS76918DBVR can be used in a variety of applications. It is especially suited for powering industrial and consumer electronics and for powering automotive and other vehicles. It is also well-suited for battery-powered applications due to its low quiescent current, allowing for longer battery life.

Working Principle

The TPS76918DBVR operates based on a feedback loop. The device is designed to maintain a stable output voltage across its output. It does this by monitoring the output voltage and comparing it to a reference voltage set by the user through an input pin. When the output voltage reaches the set reference, an error amplifier controls a p-channel MOSFET to adjust the output voltage down. Conversely, when the output voltage drops below the set reference, the MOSFET is turned off and the output voltage is maintained.

Features

The TPS76918DBVR features a wide input voltage range of 3V to 18V and an adjustable output voltage range of 0.8V to 17V. It has an adjustable voltage accuracy of +/- 0.8%. It also has an adjustable soft-start, an adjustable over-voltage protection, an adjustable over-current protection, and a shutdown mode. The device is also RoHS-compliant and has a maximum of 1.2A of output current.

Conclusion

The TPS76918DBVR is a low dropout linear voltage regulator that is ideal for industrial, automotive, consumer and environmental applications. It operates based on a feedback loop and features a wide input voltage range, an adjustable output voltage range, an adjustable voltage accuracy, adjustable soft-start, adjustable over-voltage protection, adjustable over-current protection, and a shutdown mode. The device is RoHS-compliant and has a maximum of 1.2A of output current.
