نظرة عامة على المنتج
The MIC5219-3.3YM5-TR is a 500 mA peak-output ultra-low-noise LDO linear regulator from Microchip (formerly Micrel) in a SOT-23-5 package. It provides a fixed 3.3 V output with +/-1% accuracy from a 2.5 V to 12 V input. The BYP pin with an external 470 pF capacitor enables ultra-low output noise for RF-sensitive applications. Near-zero shutdown current (<1 μA) and CMOS/TTL-compatible enable control make it ideal for battery-powered and portable devices.
