Description

The TPS7A90 device is a low-noise (4.7 µVRMS), low-dropout (LDO)voltage regulator capable of sourcing 500 mA with only 100 mV of maximum dropout to 5 V and 200 mVto 5.7 V.

The TPS7A90 output is adjustable with external resistors from 0.8 V to 5.7 V. TheTPS7A90 wide input voltage range supports operation as low as 1.4 V and up to 6.5 V.

With 1% output voltage accuracy (over line, load, and temperature) and soft-startcapabilities to reduce in-rush current, the TPS7A90 is ideal for powering sensitive analoglow-voltage devices [such as voltage-controlled oscillators (VCOs), analog-to-digital converters(ADCs), and digital-to-analog converters (DACs)].

The TPS7A90 is designed to power noise-sensitive components such as those found inhigh-speed communication, video, medical, or test and measurement applications. The very low4.7-µVRMS output noise and wideband PSRR (30 dB at 1 MHz) minimizes phasenoise and clock jitter. These features maximize performance of clocking devices, ADCs, andDACs.
