TPS72719YFFT

TPS72719YFFT Application Field and Working Principle

PMIC - Voltage Regulators - Linear

The TPS72719YFFT is a high efficiency, low power linear voltage regulator with an input voltage range of 1.15V to 5.5V and an output voltage of 0.8V to 3.3V. It is suitable for use in a wide range of applications, such as powering digital logic, video devices, battery charging, embedded systems, and more.

The TPS72719YFFT is a step-down adjustable regulator with both high efficiency and power dissipation. Its low quiescent current helps reduce system power consumption, while its high output current capability of up to 1A enable the device to source the power for more applications.

The device also contains several features to ensure efficient and reliable operation, including a thermal shutdown algorithm, overvoltage protection and undervoltage lockout.

The TPS72719YFFT is designed to operate with an output current set by an external resistor, up to a maximum of 1A output. The output voltage is adjustable through an external voltage divider, and it can be set to between 0.8V and 3.3V.

The device has a built-in low-dropout (LDO) feature that will maintain the output voltage level even when the input voltage changes. This feature helps to prevent the output voltage from dropping too low when the input voltage drops.

The TPS72719YFFT also has an enable and disable function, allowing the user to power down the device when it is not in use, reducing power consumption and extending battery life.

The device features external overcurrent protection and thermal shutdown for overcurrent and overheat conditions. Undervoltage lockout prevents the device from starting up until the input voltage reaches its threshold. Additionally, undervoltage protection ensures that the voltage output does not drop when the input voltage falls below a certain level.

The TPS72719YFFT has many important characteristics that make it a great choice in many applications. Its high efficiency and low quiescent current make it an ideal choice for low power designs. The external voltage divider allows for a wide range of output voltages, and the built-in LDO ensures the output voltage stays within the specified level even when the input voltage is changing. The integrated overcurrent and thermal protection circuits ensure safe and reliable operation, while the enable/disable function further aids in reducing power consumption. All these features make the TPS72719YFFT a highly attractive choice for a wide range of applications.
