TPS70928DBVR Application and Working Principle

PMIC stands for Power Management Integrated Circuit, and Voltage Regulators are responsible for maintaining a stable voltage buffer between the power supply and the load. Linear Voltage Regulators are used to adjust a higher input voltage to a lower output voltage. The TPS70928DBVR is an ultra-low quiescent current linear voltage regulator in a 69 SB package.

Applications

The TPS70928DBVR is suitable for use in many applications, including laptops, handheld devices, and medical equipment that require ultra-low quiescent current performance. Additionally, the TPS70928DBVR has excellent load transient response and high PSRR, making it ideal for use in industrial, automotive, and consumer applications. For example, automotive applications, such as power steering and infotainment systems, may benefit from the TPS70928DBVR\'s low dropout voltage, current limit and temperature protection capabilities, while consumer applications may be able to leverage its low ripple output capabilities.

Features and Benefits

The TPS70928DBVR is a low dropout voltage regulator with an adjustable output voltage range of 1.2V to 6.5V. Its ultra-low quiescent current and high current limit of 1.5A ensures the device will perform reliably in high power requirements. The device also offers low outputvoltage ripple and excellent load transient response.Onboard thermal shutdown and current limit protection help protect the device from excessive temperatures or currents, ensuring a stable power system. The device also has an enable control pin that allows the user to control the regulator\'s output.

Working Principle

The TPS70928DBVR is a linear voltage regulator, meaning it reduces input voltage to a stable output voltage. The regulator uses a series of transistors connected in a voltage regulator circuit. Voltage is regulated by controlling the amount of current allowed to pass through the transistors. When the input voltage is higher than the set output voltage, the transistors will turn on and allow current to pass, reducing the voltage.The TPS70928DBVR also features an Enable control pin, which allows the user to control the device\'s output. The Enable pin can be used to turn the regulator on or off, depending on the user\'s desired output voltage. Additionally, the device also offers current limit and thermal protection, ensuring stable, reliable operation in even extreme conditions.Overall, the TPS70928DBVR is an ultra-low quiescent current linear voltage regulator ideal for use in high power applications. It offers an adjustable output voltage range of 1.2V to 6.5V, current limit protection, temperature protection, and enable control. Its excellent load transient response and low ripple output make it well-suited for use in automotive, industrial, and consumer applications.
