Texas Instruments' 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 outpuft voltages are fully user-adjustable (up to 3.95 V) using a printed circuit board (PCB) layout without the need of external resistors or feed-forward capacitors, therefore 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).
