MIC5323-1.8YD5-TR

The MIC5323 is a high-performance, 300mA LDO regulator, offering extremely high PSRR and very low noise while consuming low ground current. Ideal for battery operated applications, the MIC5323 features 2% accuracy, extremely low dropout voltage (120mV @ 300mA), and low ground current at light load (typically 90μA). When disabled, the MIC5323 typically consumes less than 1μA. The MIC5323 is a uCap design operating with small ceramic output capacitors for stability, thereby reducing required board space and component cost. The MIC5323 is available in fixed output voltages and adjustable output voltages in the super compact 6-pin 2mm×2mm Thin MLF and thin SOT-23-5 package. Additional voltage options are available.
