Design Features

The TPS76050DBVTG4 is a linear voltage regulator that offers 3A step-down voltage regulation with an extended operating range of ∆Vout of ±10%. It features precise low-voltage regulation, fast transient response, ultra low noise, and remote reset functionality. The operating input voltage range is 4.5V to 24V, and the output voltage range is 0.6V to 21V. The regulator has very low quiescent current (Iq) and offers superior load regulation. It can be used as both a low-dropout (LDO) and a buck regulator.

Applications

The TPS76050DBVTG4 is suitable for a wide range of applications, including communications, industrial automation, embedded systems, digital power supplies, and general-purpose voltage regulation. It is also suitable for use in mobile devices, including laptops and tablets, as well as in smart meters, game consoles, power over Ethernet (PoE) systems, wearables, and Internet of Things (IoT) devices.

Working Principle

The TPS76050DBVTG4 is a linear voltage regulator that operates with a closed-loop control system. This control system is based on two critical feedbacks, one for output voltage and one for output current. The measured output voltage is compared with a reference voltage, and the control loop drives the gate of the switching element accordingly to maintain the output voltage. The current reference circuitry reduces the output current when either a short circuit is present or when the output voltage is below the lower voltage limit of the LDO set-point.

The TPS76050DBVTG4 has excellent thermal stability through its very low quiescent current, high efficiency, and excellent line and load regulation. It has a fast transient response while not generating excessive sideband noise, which reduces interference with analogue signal processing. The efficiency of the regulator can be increased by using a higher switching frequency and adjusting the output voltage accordingly.

Conclusion

The TPS76050DBVTG4 is a linear voltage regulator that is well-suited for many embedded applications. It features precise low-voltage regulation, fast transient response, ultra low noise, and remote reset functionality. The performance of the regulator can be further enhanced by using a higher switching frequency, and it is suitable for a wide range of applications. It is an excellent choice for applications requiring a highly efficient and reliable linear voltage regulator.
