Microchip | MIC5252-2.8YML-TR

The MIC5252-2.8YML TR is an efficient, precise CMOS voltage regulator optimized for ultra-low-noise applications. It offers 1% initial accuracy, extremely-low dropout voltage (135 mV at 150 mA) and low ground current (typically 90 µA).

The MIC5252 provides a very-low-noise output, ideal for RF applications where a clean voltage source is required. The MIC5252 has a high PSRR even at low supply voltages, critical for battery operated electronics. A noise bypass pin is also available for further reduction of output noise. The MIC5252 is available in the 6-pin 2mm 2mm MLF package and the IttyBitty® SOT235 package in a wide range of output voltages.
