Overview of TPS79928DRVTG4

The TPS79928DRVTG4 is a high-performance, low-dropout linear regulator (LDO) from Texas Instruments designed to provide a stable and reliable power supply for a wide range of applications. With an output voltage of 2.8V, this LDO is perfect for powering sensitive analog and digital circuits that require a low-noise, precise voltage source.

Key Features

• High PSRR: The TPS79928DRVTG4 boasts a high power supply rejection ratio (PSRR) of 65 dB at 1 kHz, which means it can effectively filter out supply noise and ensure a clean output voltage, making it ideal for RF and precision analog applications.
• Low Dropout: With a low dropout voltage of typically 40 mV at a 200 mA load, this LDO can operate efficiently even when the input voltage is close to the output voltage, thereby conserving power and extending battery life in portable devices.
• Low Quiescent Current: The device features a low quiescent current of 40 µA during operation and 1 µA in shutdown mode, which is critical for power-sensitive applications such as battery-operated devices.
• Stable with Low ESR Capacitors: The TPS79928DRVTG4 is stable with ceramic capacitors, which have lower equivalent series resistance (ESR) than tantalum or aluminum electrolytic capacitors, thus providing better transient response and reliability.
• Thermal Shutdown and Overcurrent Protection: Built-in safety features include thermal shutdown protection and overcurrent protection, ensuring the device and the system it powers are safeguarded against excessive temperatures and current overloads.

Applications

The TPS79928DRVTG4 is versatile and can be used in a variety of applications, such as:

• Portable and battery-powered equipment
• Wireless and RF systems
• Medical devices
