TPS72116DBVR

The TPS72116DBVR is a linear voltage regulator IC designed to deliver up to 1A of output current from an input voltage of 5V or higher. The com[any claims that the regulator is ideal for use in any applications requiring a low-power supply solution such as delayed-start circuits, battery protection circuits, and power supplies for small portable devices. This voltage regulator is highly efficient, due to its low quiescent current, low dropout voltage, and its shutdown mode. The following section describes the working principle as well as the application fields of the TPS72116DBVR.

Working Principle

The TPS72116DBVR is an NPN-based linear voltage regulator with a single output of 1A maximum. It features a wide input voltage range of 4.5V up to 18V. The voltage regulator consists of an internal NPN bipolar power transistor, a frequency compensated control loop, and several resistors for setting the output voltage and current-limit thresholds. The internal frequency-compensated control loop ensures fast and accurate regulation of output voltage. The frequency of the oscillator is set by the company at a low frequency of 7.5kHz in order to minimize power loss and noise.

Application Fields

The TPS72116DBVR can be used as a power supply solution in delayed-start circuits, battery protection circuits, and power supplies for small portable devices. Additionally, the voltage regulator can be used as a power supply for low power applications such as automotive applications, industrial control boards, actuators, computers, gaming consoles, and communications equipment. It is also suitable for use in audio and video equipment such as TVs, wearables, speakers, and more.

Benefits
