TLV70728APDQNR

TLV70728APDQNR Description

The TLV70728APDQNR is a high-performance, low-dropout linear voltage regulator from Texas Instruments, designed to deliver a fixed 2.8V output voltage with a maximum input voltage of 5.5V. This regulator is part of the TLV707 series and is optimized for low quiescent current (Iq) and high power supply rejection ratio (PSRR), making it ideal for applications where efficiency and noise reduction are critical. The device features a low dropout voltage of 0.3V at 150mA, enabling it to operate efficiently even when the input-to-output voltage difference is minimal. The TLV70728APDQNR is available in a surface-mount package, specifically in tape and reel (TR) format, and is compliant with both REACH and RoHS3 standards, ensuring environmental sustainability and regulatory compliance.

TLV70728APDQNR Features

• Low Quiescent Current: The TLV70728APDQNR operates with a quiescent current of only 50 µA, significantly reducing power consumption in standby mode, which is crucial for battery-powered and energy-efficient applications.
• High PSRR: The regulator boasts a power supply rejection ratio of 70dB at 100Hz, which decreases to 50dB at 1MHz. This high PSRR ensures minimal noise transmission from the input to the output, providing a clean and stable voltage supply for sensitive analog circuits.
• Fixed Output Voltage: The device offers a fixed output voltage of 2.8V, eliminating the need for external resistors to set the output voltage, simplifying the design process.
• Current Limiting and Enable Control: The TLV70728APDQNR includes current limiting features to protect against overcurrent conditions and an enable pin to control the regulator's operation, providing additional flexibility and control.
• Protection Features: The regulator is equipped with overcurrent protection, overtemperature protection, and under-voltage lockout (UVLO) to safeguard the device and connected circuits from damage due to abnormal operating conditions.
• Surface-Mount Compatibility: The surface-mount package type ensures ease of integration into modern printed circuit boards (PCBs), facilitating compact and reliable designs.
• Regulatory Compliance: The TLV70728APDQNR is REACH unaffected and RoHS3 compliant, ensuring it meets stringent environmental and safety standards, making it suitable for global deployment.
