The MIC5259 is an efficient CMOS voltage regulator optimized for low-noise applications. It offers 1.5% initial accuracy, low dropout voltage (300mV at 300mA) and low ground current (typically 105A at light load). The MIC5259 provides a verylow-noise output, ideal for RF applications where a clean voltage source is required. The MIC5259 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.
