Voltage regulators are the essential components in digital circuit design and typically provide a steady voltage output from varying voltage inputs. The Texas Instruments TLV7113030DDSET linear voltage regulator is optimized for use in low-power automotive and IoT applications. The circuit offers ultra-low quiescent current and shut down mode operation down to 0.2V. This article will explain the application field of the TLV7113030DDSET and its working principle.

Application Field

The TLV7113030DDSET is a low-power, low-voltage linear voltage regulator specifically designed to support automotive and IoT applications. The circuit utilizes an internal short-circuit and thermal protection circuit to ensure long-term reliability and safety. This small, 3mm x 3mm device is capable of supplying up to 300mA and can operate over a wide temperature range of -40 to 125°C. This makes it suitable for applications such as automotive digital power supplies, IoT endpoints, battery-operated systems, industrial and medical sensors.

Working Principle

The TLV7113030DDSET works by sensing the voltage differential across the two inputs and using an internal feedback regulation circuit to adjust the output voltage until it matches the desired input voltage. It does this by comparing the output voltage to the reference voltage and then using an error amplifier to adjust the output voltage until both voltages are equal. The device typically contains two transistors: a pass transistor, which is used to regulate the current, and a control transistor, which is used to control the pass transistor.

The control transistor works by controlling the pass transistor through a feedback loop. If the output voltage is too low, the control transistor increases the voltage to the pass transistor, thus increasing the output voltage. On the other hand, if the output voltage is too high, the control transistor decreases the voltage to the pass transistor, thus decreasing the output voltage. Once the output voltage matches the reference voltage, the device goes into a steady state. This process is known as voltage regulation.

Conclusion

The Texas Instruments TLV7113030DDSET is an ideal voltage regulator for automotive, IoT, and battery-operated systems. It offers reliable operation over a wide temperature range and can deliver up to 300mA. The circuit works by sensing the voltage differential across its inputs and uses an internal feedback regulation circuit to adjust the output voltage until it matches the desired input voltage. In summary, the TLV7113030DDSET is a great choice for low power applications where precise voltage regulation is required.
