TPS72116DBVT is a low-power voltage regulator from Texas Instruments. It is a linear regulator which helps regulate the output voltage. It is a versatile regulator and is commonly used for various applications such as supervisory circuits and digital power supplies. This device provides a wide input voltage range, low quiescent current, and low dropout voltage.

The device comes with a dual-channel configuration and has an adjustable output current of up to 1.5A and a maximum output voltage of 11.25V. It has a wide operating temperature range of -40˚C to +125˚C. The TPS72116DBVT provides accurate voltage regulation, low ripple, and fast transient response. Additionally, this device features a reverse-current and overload protection.

The working principle of TPS72116DBVT is based on a three-terminal regulator operating as a constant-current source. It consists of an internal voltage reference, a bandgap reference and error amplifier, an internal current sense circuit, an output switch, and a current limiter. When an input voltage is applied to the device, the error amplifier compares the output voltage level to the internal voltage reference and adjusts the current through the output switch accordingly.

When the output current needs to be adjusted, the external resistor is used to set the current limit level. The device will limit the output current to the external resistor set level. The device can be trimmed to a 0.5% accuracy with a trimming resistor located at the Ref Pin of the device. This provides an effective voltage regulation over a wide input voltage range.

The TPS72116DBVT is designed for use in various applications such as automotive, industrial, and communications applications. It is also suitable for systems requiring low-noise operation. It is available in a variety of packages for easy installation. In addition, this device is RoHS compliant, making it an environmentally friendly solution.

In conclusion, the TPS72116DBVT from Texas Instruments is a low power, low dropout voltage, and low quiescent current linear regulator. It is capable of providing accurate voltage regulation and is suitable for a wide range of applications from automotive to communications applications. Its features make it an ideal choice for a variety of systems for efficient power delivery.
