Description

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 at 300mA), and low ground current at light load (typically 90µA). When disabled, the MIC5323 typically consumes less than 1µA. The MIC5323 is a µCap 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 thin SOT-23-5 package. Additional voltage options are available.
