The MIC5209-4.2YS-TR is a fixed-output low dropout linear regulator from Microchip Technology, delivering a stable 4.2V at up to 500mA. Its low 170µA quiescent current and 0.6V dropout voltage make it an efficient choice for battery-operated and power-sensitive applications. With 75dB PSRR at 120Hz, it effectively suppresses input ripple, ensuring clean power for sensitive electronics. Housed in a compact SOT-223-3 package, this regulator is ideal for space-constrained designs.
- Compact Package: SOT-223-3 footprint saves board space for miniaturized designs.
- Extended Battery Life: Ultra-low 170µA quiescent current minimizes standby power consumption, ideal for portable devices.
- High Noise Rejection: 75dB PSRR at 120Hz filters out ripple, providing clean power for sensitive analog and digital circuits.
- Low Dropout Operation: 0.6V dropout at 500mA allows operation from nearly depleted batteries, maximizing usable energy.
