Overview of Texas Instruments TLV70228DSET

The Texas Instruments TLV70228DSET is a high-performance, low-dropout (LDO) voltage regulator optimized for applications requiring low noise, high power supply rejection ratio (PSRR), and low quiescent current. This regulator is designed to deliver up to 300 mA of continuous output current with a dropout voltage of just 250 mV at full load, making it an excellent choice for battery-powered and low-power applications.

Key Features

• Output Voltage: The TLV70228DSET provides a fixed output voltage of 2.8V, which is suitable for powering sensitive analog and digital circuits.
• High PSRR: With a PSRR of 68 dB at 1 kHz, this LDO can suppress power supply noise effectively, ensuring a stable output voltage even in the presence of fluctuations in the input supply.
• Low Noise: The device is designed to minimize output voltage noise, making it ideal for RF and precision analog applications that require a clean power supply.
• Low Quiescent Current: It features a low quiescent current of typically 34 µA, which is critical for extending battery life in portable devices.
• Thermal Shutdown and Overcurrent Protection: These safety features protect the device and the load from damage due to excessive temperatures or current.
• Small Package Size: The TLV70228DSET is available in a small, 1.5mm x 1.5mm, 6-pin SON package, which is ideal for space-constrained applications.
