Linear & Switching Voltage Regulators

TPS79650DRBT Description

The TPS79650DRBT is a high-performance linear regulator designed for applications requiring a stable 5V output at up to 1A of current. Manufactured by Texas Instruments, this device is part of the Power Management (PMIC) category and is housed in an 8-lead SON package, suitable for surface mount applications. The TPS79650DRBT features a fixed output voltage of 5V and operates with an input voltage range up to 5.5V. It boasts a low dropout voltage of 0.3V at 1A, ensuring efficient power conversion even under heavy load conditions. The regulator includes a quiescent current of 385 µA, which helps in minimizing power consumption during standby modes.

TPS79650DRBT Features

The TPS79650DRBT offers several key features that set it apart from similar linear regulators. It includes an enable control feature, allowing users to turn the regulator on and off as needed, which is particularly useful for power management in complex systems. The device provides robust protection mechanisms such as over current, over temperature, reverse polarity, and under voltage lockout (UVLO), ensuring reliable operation and safeguarding against various fault conditions. The regulator also has a high power supply rejection ratio (PSRR) ranging from 59dB at 100Hz to 42dB at 100kHz, which helps in filtering out noise from the input power source and maintaining a clean output voltage.

TPS79650DRBT Applications

The TPS79650DRBT is ideal for a wide range of applications due to its stable output voltage, high efficiency, and comprehensive protection features. It is particularly well-suited for consumer electronics, portable devices, and industrial systems where a reliable 5V power supply is essential. The low dropout voltage makes it suitable for battery-powered applications, where the input voltage may drop close to the output voltage as the battery discharges. The enable feature allows for dynamic power management, making it a good fit for systems that require power sequencing or sleep modes to conserve energy.

Conclusion of TPS79650DRBT

In summary, the TPS79650DRBT is a versatile and reliable linear regulator designed to meet the demands of modern power management applications. Its fixed 5V output, low dropout voltage, and comprehensive protection features make it an excellent choice for a variety of consumer and industrial applications. The enable control and high PSRR further enhance its performance, making it a standout option in the Power Management (PMIC) category. With its robust design and efficient operation, the TPS79650DRBT ensures stable power delivery and long-term reliability, making it a preferred choice for engineers and designers in the electronics industry.
