Texas Instruments TPS7A92 Low Noise Low Dropout Voltage Regulator
Texas Instruments TPS7A92 Low Noise Low Dropout Voltage Regulator device is a low-noise (4.8µVRMS), low-dropout (LDO) voltage regulator capable of sourcing 2A with only 180mV of dropout. The TPS7A92 output is adjustable with external resistors from 0.8V to 5.2V. The TPS7A92 wide input-voltage range supports operation as low as 1.4V and up to 6.5V. With 1% output voltage accuracy (over the line, load, and temperature) and soft-start capabilities to reduce inrush current, the TPS7A92 is ideal for powering sensitive analog low-voltage devices. These types of devices include voltage-controlled oscillators (VCOs), analog-to-digital converters (ADCs), digital-to-analog converters (DACs), high-end processors, and field-programmable gate arrays (FPGAs). The TPS7A92 is designed to power noise-sensitive components such as those found in high-speed communication, video, medical, or test, and measurement applications.
