Dual low-noise LDO voltage regulator ideal for powering sensitive analog low-voltage devices

The Texas Instruments TPS7A88-Q1 is a dual, low-noise (4µVRMS), low-dropout (LDO) voltage regulator capable of sourcing 1A per channel with 250mV of maximum dropout. The device provides the flexibility of two independent LDOs and approximately 50% smaller solution size than two single-channel LDOs. Each output is adjustable with external resistors from 0.8V to 5.15V. The device 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 device is ideal for powering sensitive analog low-voltage devices such as VCOs, ADCs, DACs, high-end processors, and FPGAs. The device is designed to power noise-sensitive components such as those found in RF, radar communications, and telematic applications. The low 4µVRMS output noise and wideband PSRR (40dB at 1MHz) minimizes phase noise and clock jitter. These features maximize performance of clocking devices, ADCs, and DACs. It features wettable flanks for simple optical inspection.
