Product Overview: TPS79926YZUR by Texas Instruments

The TPS79926YZUR is a high-performance, low-dropout linear regulator (LDO) from Texas Instruments designed to deliver a stable and precise voltage supply. This regulator is tailored for applications requiring a low noise, high PSRR (Power Supply Rejection Ratio), and low quiescent current, making it an ideal choice for sensitive RF and analog circuitry.

Key Features

• Highly Stable Output: With an output voltage of 2.6V, the TPS79926YZUR ensures a stable and reliable power supply, which is crucial for maintaining the performance of sensitive electronic components.
• Low Dropout: The LDO features a low dropout voltage, which enables it to continue providing a regulated output even when the supply voltage is very close to the output voltage, thus maximizing efficiency.
• Low Noise: This device exhibits exceptionally low noise characteristics, with a typical output noise of 30 µVRMS for 10 Hz to 100 kHz, making it suitable for noise-sensitive applications such as audio or RF systems.
• High PSRR: With a high PSRR of 70 dB at 1 kHz, the TPS79926YZUR effectively filters input supply noise, which is particularly beneficial for maintaining signal integrity in precision analog circuits.
• Low Quiescent Current: The device operates with a low quiescent current of typically 40 µA, contributing to energy conservation in battery-powered devices.
• Thermal and Overcurrent Protection: Built-in thermal shutdown and overcurrent protection mechanisms safeguard the device and the application against excessive temperatures and current conditions.
