This makes it an ideal choice for use in vehicles with limited space, such as motorcycles. In addition, the TPS65105RGERG4 is available in both – 40°C to +125°C and +85°C to +105°C temperature ranges, making it suitable for use in a range of automotive applications. In addition, the low dropout voltage of the TPS65105RGERG4 makes it an ideal choice for use in battery powered systems.

Working Principle

The TPS65105RGERG4 is an adjustable voltage regulator which uses a constant-voltage switching topology. It is designed to provide a low noise output voltage with high accuracy and low output noise. The regulator utilizes a shared control voltage which is provided by the power transformer or an external source. The output voltage is controlled by means of the regulation pot-meter, that is connected to the voltage regulator’s output. Once the desired output voltage is set, the regulator adjusts its current draw from the transformer or external source to maintain the desired output voltage.

The TPS65105RGERG4 also includes an on-chip REF-LREF circuit for controlling the output voltage. This circuit consists of an adjustable internal reference voltage that is generated using a resistor divider network connected to an external voltage reference pin. The voltage at this pin is used to set the output voltage of the regulator by means of the REF-LREF pin. The REF-LREF voltage can be adjusted by connecting a resistor divider network between the external reference pin and the GND pin of the TPS65105RGERG4.

In addition to the REF-LREF circuit, the TPS65105RGERG4 also features an on-chip voltage reference. This voltage reference is used to adjust the output voltage of the regulator. The voltage reference is adjusted by connecting a resistor divider network between the external reference pin and the GND pin of the TPS65105RGERG4. Once the voltage reference is set, the output voltage of the TPS65105RGERG4 will be regulated in accordance with the voltage reference.

The TPS65105RGERG4 also utilizes an on-chip current limit circuit. This circuit ensures that the regulator does not draw too much current from the power source. This is particularly important for battery powered systems, where excessive current draw can significantly reduce the battery life. The current limit circuit is adjustable and is used to set the maximum current that the regulator can draw from the power source.

The TPS65105RGERG4 also features various protection circuits. These circuits are designed to protect the regulator and the load from damage due to excessive current draw or over-voltage. They also protect the regulator and the load from damage due to thermal runaway or under-voltage.

Conclusion

The TPS65105RGERG4 is a special purpose voltage regulator designed for use in low power applications which require high accuracy power supply regulation. It is an adjustable voltage regulator which utilizes an on-chip REF-LREF circuit and voltage reference. Additionally, it features an on-chip current limit circuit and various protection circuits. The TPS65105RGERG4 is a popular choice for use in embedded systems and automotive applications due to its small form factor, its high switching frequency, and its low dropout voltage. It is ideal for use in applications such as embedded microcontrollers, as well as in battery powered systems where power efficiency is a priority.
