The TPS720115QDRVRQ1 is an integrated voltage regulator that belongs to the category of linear regulators. It maintains an output voltage in a range of 0.8V up to 7V that is suitable for various applications.The TPS720115QDRVRQ1 voltage regulator incorporates a small outline package of 6-pin SOT-23 with low-dropout voltage and low-quiescent current features. Also, this voltage regulator features an adjustable output voltage. It has an operating temperature range of -40°C to 125°C and is made with improved device total harmonic distortion and improved output regulation transient response.TPS720115QDRVRQ1 is mainly used in Point-Of-Load applications and systems that require higher efficiency and low output voltage ripple. It supports low output capacitance and dynamic performance to achieve fast transient response and superior performance including power and line regulation.Moreover, TPS720115QDRVRQ1 linear voltage regulator offers precision output voltage and thermal protection shutdown to prevent the device damage from operating in a short-circuit and thermal hot spots condition in a given applications.Working PrincipleThe TPS720115QDRVRQ1 is a linear voltage regulator. It works on the principle of a series regulator. A series regulator is a circuit configuration where the output voltage is set by adjusting the voltage drop across a series element. In a simple series voltage regulator, the series element can be a diode, transistor or diode-transistor combination.In TPS720115QDRVRQ1 linear voltage regulator the series element is a transistor. It includes an input terminal and an output terminal connected through the transistor. The output voltage is set by adjusting the voltage drop across the transistor.The TPS720115QDRVRQ1 features a low dropout (LDO) architecture which means that the input voltage should be quite close to the output voltage (less than 2V-3V). That allows the TPS720115QDRVRQ1 to operate with higher efficiency than conventional linear regulators which typically require a very large input-output voltage differential for operation. The low voltage drop across the transistor results in excellent power efficiency of 90% or higher. The TPS720115QDRVRQ1 linear voltage regulator provides a constant output voltage with good line and load regulation. It is important to note that the linear regulator is more stable in regulating the output voltage as compared to the switching regulators. This is due to the fact that a linear regulator can provide a more steady output voltage and can be much more accurate.The TPS720115QDRVRQ1 linear regulator includes a shutdown control input that can be used to minimize power consumption. The shutdown pin enables the regulator to be shut down if the output is not needed, thereby saving power and reducing power dissipation.The TPS720115QDRVRQ1 also includes an Enable input. This input is used to connect other regulating circuits and provides information about the output voltage status. The enable input can be used to optimize the performance and to ensure that the output voltage remains constant.The TPS720115QDRVRQ1 linear voltage regulator also includes short-circuit protection and thermal protection features which help protect the device from any damage due to overcurrent or over temperature.In addition, the TPS720115QDRVRQ1 linear voltage regulator employs a low-noise current-mode control. This circuit topology helps in maintaining a constant output voltage with fast transient response under varying line and load conditions.Application FieldThe TPS720115QDRVRQ1 voltage regulator is suitable for many point-of-load applications. It is used in power conditioning systems such as adjustable output voltage power supplies, microprocessors, digital signal processors, data converters, portable electronics, etc. In addition, the TPS720115QDRVRQ1 voltage regulator is used in system-on-a-chip applications, such as Ethernet switches, micro-controllers, baseband radios, and other portable electronic devices. The device also provides a high switching frequency to ensure that the output voltage does not deviate from the nominal voltage even during fast transients.ConclusionThe TPS720115QDRVRQ1 is an integrated linear voltage regulator with low-dropout voltage and low-quiescent current features. It is particularly suitable for Point-Of-Load applications and provides an adjustable output voltage. It also includes short-circuit protection and thermal shutdown to ensure the device against any damage due to overcurrent or over temperature. The TPS720115QDRVRQ1 is also suitable for Ethernet switches, power conditioning systems, microprocessors, digital signal processors, data converters, and other portable electronic devices.
