Description

The TPS7A90 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 mV to 5.7 V. The TPS7A90 output is adjustable with external resistors from 0.8 V to 5.7 V. The TPS7A90 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-start capabilities to reduce in-rush current, the TPS7A90 is ideal for powering sensitive analog low-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 in high-speed communication, video, medical, or test and measurement applications. The very low 4.7-µVRMSoutput noise and wideband PSRR (30 dB at 1 MHz) minimizes phase noise and clock jitter. These features maximize performance of clocking devices, ADCs, and DACs.
