TPS7A6050QKVURQ1 is a low noise and low power consumption linear regulator integrated circuit that belongs to the Power Management Integrated Circuit (PMIC) voltage regulator\'s linear category. It features a wide 2.2V to 15V adjustable input voltage, a low 0.05%/V Line regulation and a low 0.1%/V Load regulation to provide a wide range of applications.

The output voltage of the TPS7A6050QKVURQ1 can be adjusted with an external resistor divider in an adjustable range between 3V to 15V which makes the device more suitable for various applications. Additionally, the TPS7A6050QKVURQ1 integrates an internal temperature sensor that provides a temperature monitoring function when used with an external NTC thermistor. This allows the TPS7A6050QKVURQ1 to maintain output voltage within accuracy limits even with changes in temperature.

The TPS7A6050QKVURQ1 excels in low noise performance and can deliver up to 265mA output current in a low noise environment. This allows designers to reduce power and opt for a linear solution in many noise sensitive system applications. With a fast transient response, and a wide range of operating temperature, the TPS7A6050QKVURQ1 can meet the system level requirements, even in harsh and demanding operating environment.

The working principle of the TPS7A6050QKVURQ1 is based on a standard dc-dc buck regulator. It employs an internal P-channel MOSFET which operates as a switching transistor. The conduction of the MOSFET is controlled by an external current source and the output voltage is set by a resistive network connected to the external senses node. The internal current source fixes the circuit frequency and sets the peak currents of the MOSFET. When the MOSFET is conducting, the internal current source limits the current trough the MOSFET, thus providing the output voltage regulation.

The TPS7A6050QKVURQ1 features an undervoltage lock-out (UVLO) circuit which prevents operation during inadequate supply voltage. To increase the UVLO threshold, an external resistor divider can be used and the UVLO can be disabled by grounding the UVLO pin.

The TPS7A6050QKVURQ1 is available in SOT-223-5 package and offers many advantages over alternative solutions in terms of low noise, small form factor and low power consumption. It is ideal for applications such as automotive, audio, industrial, and medical systems, as well as point-of-load (POL) and data-line termination.
