MIC5353

In Production

The MIC5353 is a high performance, single-output, ultra-low LDO (ULDO™) regulator, offering a low total output noise of 30µVrms. The MIC5353 is capable of sourcing 500mA output current and offers high PSRR and low output noise, making it an ideal solution for RF applications. The MIC5353 provides 2% accuracy, extremely low dropout voltage (160mV at 500mA), and low ground current (typically 90µA) making it ideal for battery-operated applications. When disabled, the MIC5353 enters a zero off-mode current state, thereby drawing almost no current. ...
