[TI] TPS7A8500RGRR Low-Noise (4.4 µVRMS), Low-Dropout Linear Regulator (LDO)

Shenzhen Mingjiada Electronics Co., Ltd. — Long-term supplier of TI TPS7A8500RGRR high-performance, low-noise, low-dropout linear regulator (LDO)

Product Core Description  

The TPS7A8500RGRR is a high-performance, ultra-low-noise, high-current LDO regulator. It employs advanced manufacturing processes and design to deliver an impressive 4.4 µVRMS ultra-low output noise (10 Hz to 100 kHz) and excellent power supply ripple rejection ratio (PSRR) while providing up to 5A output current.

TPS7A8500RGRR Product Features

Ultra-Low Noise: With only 4.4 µVRMS of wide-band noise, it significantly reduces interference with high-precision analogue circuits (such as ADCs, DACs, PLLs, VCOs, and sensors) and RF circuits (such as local oscillators (LOs)). This is the core competitive advantage of the TPS7A8500RGRR.

High Current & Low Dropout: Maximum output current of 5A with extremely low dropout voltage (typical value) at full load, effectively improving power conversion efficiency, especially when the input voltage is close to the output voltage, thereby extending the runtime of battery-powered devices.

Excellent PSRR (High PSRR): Provides outstanding power supply ripple suppression capability across a wide frequency range (e.g., >70dB at 1kHz), effectively filtering out noise and ripple from upstream switching power supplies or batteries, providing a ‘quiet’ voltage to the load.

High Accuracy and Flexibility: High output voltage accuracy (±1% typical value), with flexible adjustment via an external resistor within the range of 0.8V to 5.2V to meet the needs of different circuits.

Comprehensive Protection: Integrated overcurrent protection (OCP), over-temperature shutdown (TSD), and enable (EN) control functions ensure system and device safety and reliability.

Compact Package: Utilises a 20-pin VQFN (RGR) package.
