500mA、低噪声、高 PSRR、高精度、可调节超低压降稳压器 10-SON -40 to 125
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 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-µVRMS output 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.
