TPS79433DCQG4 is a high-performance, four-phase linear voltage regulator presented by Texas Instruments. It carries four independent low-dropout regulators, each output with a maximum of 2A current capacity. As a four-phase linear voltage regulator, its application field starts from DC applications to very low noise AC applications.

The TPS79433DCQG4 can be utilized in a wide range of applications such as DC power management, automotive safety systems, wireless communication equipment and various professional audio components. It is used in mobile applications, machine-to-machine communication and industrial data processing systems, as well as in low-emission/low-power systems, such as solar systems, commercial building automation equipment and other green energy systems. Being a highly efficient linear regulator, it consumes very low power and has high current output, making it efficient for a wide range of applications.

In regards to an overview of the TPS79433DCQG4 working principle, the four outputs are independently regulated and can support a maximum of 2A current each. It includes short-circuit protection and over-voltage protection. The output voltage is controlled by an external voltage reference VREF, and is regulated by a controlled transconductance error amplifier, which is used to obtain a constant output voltage when the input voltage is varying. The device also has a proprietary internal current limit circuit, which limits the maximum output current for each channel. Moreover, there is a reverse current protection, which limits the reverse current to safe levels.

The device also features advanced thermal shutdown control, which protects it from current faults. This makes it ideal for systems which require highly efficient power regulation, such as automotive safety systems, where over-current protection is essential. This also helps when expensive components are connected directly to this device, safe-guarding the system against damages.

The TPS79433DCQG4 provides four outputs, each capable of delivering 2A current with low supply current, making it ideal for a wide range of applications such as DC power management and automotive safety systems. Its versatile design includes short-circuit protection and over-voltage protection, along with advanced thermal shutdown control. It is a highly efficient linear regulator and is ideal for use in green energy systems, as it provides low supply current at high current outputs.
