The TPS7A4700 from Texas Instruments is a high-performance adjustable LDO regulator, delivering up to 1A with output from 1.4V to 20.5V. It features ultra-low noise (4.16 µVrms) and high PSRR (78dB at 1kHz), making it ideal for noise-sensitive applications. The 20-VQFN package and 1mA quiescent current balance performance and efficiency.
- Ultra-Low Noise (4.16 µVrms): Provides clean power for high-fidelity audio and precision analog circuits.
- High PSRR (78dB at 1kHz): Excellent ripple rejection for stable output.
- High Output Current (1A): Supports demanding loads like FPGAs and DSPs.
- Wide Input Range (up to 36V): Flexible for automotive and industrial supplies.
