The TPS76728QD is a high-performance, low-dropout (LDO) voltage regulator designed and manufactured by Texas Instruments. This LDO regulator offers the benefits of low dropout voltage, fast transient response, and excellent power supply rejection ratio (PSRR), making it ideal for a variety of applications, including but not limited to, powering microprocessors, FPGAs, and other digital ICs that require a stable and precise voltage supply.

Key Features

• Output Voltage: The TPS76728QD provides a fixed output voltage of 2.8V, which is suitable for logic circuits and other standard digital components.
• Output Current: It is capable of delivering up to 1A of continuous output current, ensuring sufficient power for most moderate load applications.
• Dropout Voltage: The low dropout voltage of typically only 350 mV at full load minimizes power loss and improves efficiency, which is critical for battery-powered devices.
• Thermal Protection: It includes built-in thermal protection that shuts down the regulator to prevent damage if the device becomes too hot.
• Package: The device comes in a PowerPAD™ package, which enhances thermal performance and is suitable for space-constrained applications.
• PSRR: High PSRR of 50 dB at 1 kHz ensures stable output voltage despite variations in input voltage, which is particularly important for sensitive RF and audio applications.
