In addition to low noise, the LT3045 linear regulator from Linear Technology provides a PSRR (power supply rejection ratio) of >90 dB to 10 kHz and >70 dB to 2.5 MHz, quieting noisy or high-ripple input supplies. The LDO regulator’s ultralow spot noise of only 2 nV/√Hz at 10 kHz and RMS noise of just 0.8 µVRMS from 10 Hz to 100 kHz make it well-suited for noise-sensitive applications, such as PLLs, VCOs, instrumentation, and medical equipment.
