The TPS7A92 is a low-noise (4.6µVRMS), low-dropout (LDO) voltage regulator capable of sourcing 2A with only 180mV of maximum dropout.

The TPS7A92 output is adjustable with external resistors from 0.8V to 5.2V. The TPS7A92 wide input voltage range supports operation as low as 1.4V and up to 6.5V.

With 1% output voltage accuracy (over line, load, and temperature) and soft-start capabilities to reduce in-rush current, the TPS7A92 is designed for powering sensitive analog low-voltage devices [such as voltage-controlled oscillators (VCOs), analog-to-digital converters (ADCs), digital-to-analog converters (DACs), high-end processors, and field-programmable gate arrays (FPGAs)].

The TPS7A92 is designed to power noise-sensitive components such as components found in high-speed communication, video, medical, or test and measurement applications. The very low 4.6µVRMS output noise and wideband PSRR (40dB at 1MHz) minimizes phase noise and clock jitter. These features maximize performance of clocking devices, ADCs, and DACs.
