MIC5353-3.3YMT-TR

MIC5353-3.3YMT-TR is a high-performance, single-output, ultra-low LDO regulator, offering a low total output noise of 30μVRMS. The MIC5353 is capable of sourcing a 500mA output current and offers high-PSRR and low-output noise, making it an ideal solution for RF applications. It 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. The application includes mobile phones, GPS, PDAs, PMP, handhelds, portable electronics, digital still and video cameras, and digital TV.
