LDO Regulator Pos 2.6V 0.15A 5Pin TSOT-23
General Description
The MIC5255 is an efficient, precise 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. A noise bypass pin is also available for further reduction of output noise.
