The ET5B0XX is a low-noise (6µVRMS), low- dropout voltage regulator (LDO) capable of sourcing a 2A load with low dropout. The output voltages are fully user-adjustable 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 5V with the use of external resistors. The device supports very low input voltages (down to 1.1V) with the use of an additional BIAS rail.
With very high accuracy, remote sensing, and soft-start capabilities to reduce inrush current, the ET5B0XX is ideal for powering high-current, low-voltage devices such as high-end microprocessors and field-programmable gate arrays.
The ET5B0XX is designed to power-up noise-sensitive components in high-speed communication applications. The very low-noise, 6µVRMS device output and high broad-bandwidth PSRR minimizes phase noise and clock jitter in high-frequency signals. These features maximize performance of clocking devices, analog-to-digital converters, and digital-to-analog converters.
