MICREL MIC5255 Manual

The MIC5255 is a high-precision low-noise CMOS voltage regulator optimized for ultra-low-noise applications. It offers 1% initial accuracy, extremely-low dropout voltage (135mV at 150mA) and low ground current (typically 90µA). The MIC5255 provides a very-low-noise output, ideal for RF applications where a clean voltage source is required.
