TPS73130DBVT is a member of Texas Instruments’ TPS73xxx family of low-dropout linear regulators. The components of the TPS73xxx family are pin-to-pin compatible and available in fixed output voltages from 0.6V to 5.0V. The TPS73xxx family of linear regulators provide a cost-effective, low-noise and low-dropout solution for portable consumer, computing and communication designs. Standard features of the TPS73xxx family of linear regulators include low-noise operation, high-input voltage robustness and low-quiescent current.

The TPS73130DBVT is particularly suited for low-power and board-level applications. With only 1.5 μA quiescent current, the TPS73130DBVT is able to maintain low power dissipation while still maintaining high accuracy across the full input range. Additionally, the TPS73130DBVT offers a very low dropout voltage of 1.3 V at maximum load current.

The TPS73130DBVT is an electronically adjustable device that delivers a precise output voltage from an input voltage in the range of 1.1V to 6V. The output voltage can be adjusted from 0.6V to 4.5V, virtually any voltage within this range can be programmed via its external reference voltage. It operates at a temperature range of -40°C to 125°C and it is rated to support a maximum output current of up to 250mA.

The TPS73130DBVT works on the same principle as other linear regulators. Its built-in FET controlling the current ensures accurate output voltage over a wide range of line and load conditions. This FET acts as a current controlled switch, whose resistance is controlled by both the voltage applied to its gate terminal and the input current. Whenever the voltage across the output is lower than its reference voltage, the FET is driven in full open position, conducting a maximum allowable current. This current behaviour is used to maintain the output voltage at the reference voltage level.

The TPS73130DBVT offers two main advantages. Firstly, its high-efficiency regulation at low power levels reduces the power dissipation significantly compared to other linear regulators. Secondly, its precision voltage regulation also permits a very small footprint. With its small size, it requires less area on the printed circuit board.

In addition, the TPS73130DBVT also has a built-in Over-Temperature Protection (OTP) that automatically shuts down the regulator if the internal temperature of the IC exceeds its pre-set threshold. This OTP feature prevents the regulator from operating in unsafe conditions and prolongs the life of the product.

Applications for the TPS73130DBVT include powering integrated circuits in portable electronics and computing, communications, industrial control and home appliances. It is particularly suitable for applications where high voltage surge is a concern. The device provides a good combination of performance and cost-effectiveness and its wide operating range makes it suitable for a variety of different applications.

To conclude, the TPS73130DBVT is a feature-rich, low-dropout linear regulator that is suitable for low-power and board-level applications. Its extremely low quiescent current, high input voltage robustness and low-noise operation makes it an ideal choice for powering various electronic circuits. Its Over-Temperature Protection feature adds an extra layer of safety and protection and its small footprint reduces power dissipation, making it an ideal choice for cost-sensitive applications.
