Description
The TPS7A8300 is a low-noise (6 µVRMS), low-dropout voltage regulator (LDO) capable of sourcing a 2-A load with only 125 mV of maximum dropout.
The TPS7A8300 output voltages are fully user-adjustable (up to 3.95 V) using a printed circuit board (PCB) layout without the need of external resistors, thus reducing overall component count. For higher output voltage applications, the device achieves output voltages up to 5 V with the use of external resistors. The device supports very low input voltages (down to 1.1 V) with the use of an additional BIAS rail.
With very high accuracy (1% over line, load, and temperature), remote sensing, and soft-start capabilities to reduce inrush current, the TPS7A8300 is ideal for powering high-current, low-voltage devices such as high-end microprocessors and field-programmable gate arrays (FPGAs).
The TPS7A8300 is designed to power-up noise-sensitive components in high-speed communication applications. The very low-noise, 6-µVRMS device output and high broad-bandwidth PSRR (40 dB at 1 MHz) minimizes phase noise and clock jitter in high-frequency signals. These features maximize performance of clocking devices, analog-to-digital converters (ADCs), and digital-to-analog converters (DACs).
For applications where positive and negative low-noise rails are required, consider TIs TPS7A33 family of negative high-voltage, ultralow-noise linear regulators.
