REQUEST A QUOTE
The TPS7A92 is a low-noise (4.8 µVRMS), low-dropout(LDO) voltage regulator capable of sourcing 2 A with only 180 mV of dropout.
The TPS7A92 output is adjustable with external resistors from 0.8 V to 5.2 V. TheTPS7A92 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 TPS7A92 is ideal for powering sensitive analoglow-voltage devices [such as voltage-controlled oscillators (VCOs), analog-to-digital converters(ADCs), digital-to-analog converters (DACs), high-end processors, and field-programmable gatearrays (FPGAs)].
The TPS7A92 is designed to power noise-sensitive components such as those found inhigh-speed communication, video, medical, or test and measurement applications. The very low4.6-µVRMS output noise and wideband PSRR (40 dB at 1 MHz) minimizes phasenoise and clock jitter. These features maximize performance of clocking devices, ADCs, andDACs.
