MIC5209-3.3YS-TR MICROCHIP Linear

The MIC5209-3.3YS-TR from Microchip is a fixed 3.3V low‑dropout linear regulator delivering 500mA output with ±1% accuracy, purpose‑built for handheld, battery‑powered devices. For selection, key specifications include a 2.5–16V input range, a very low dropout voltage of typically 10mV at light loads and under 500mV at full load, 170µA quiescent current, 75dB PSRR at 120Hz, and an enable pin allowing near‑zero shutdown current to extend battery life. Built‑in protection features over‑current, over‑temperature, and reverse‑polarity faults. In application, it excels in portable consumer electronics, cellular telephones, notebook and palmtop computers, battery‑powered IoT sensor nodes and wearables, automotive ECUs and sensor modules, industrial automation and control systems, SMPS post‑regulation, and noise‑sensitive RF or analog circuits where a compact SOT‑223 surface‑mount package and reliable –40°C to +125°C operation are essential.
