The MIC5209-1.8YM is a fixed 1.8V LDO regulator from Microchip Technology, delivering up to 500mA. With a dropout of 0.6V at full load and 170µA quiescent current, it is optimized for low-power and battery-operated designs. The 8-SOIC package provides a compact footprint. Its 75dB PSRR at 120Hz ensures stable output for noise-sensitive applications.
- Stable Low Voltage: 1.8V output ideal for modern digital ICs.
- High Efficiency: Low quiescent current reduces power waste.
- Excellent Noise Rejection: 75dB PSRR protects sensitive loads.
- Compact SOIC-8: Easy to solder and thermally adequate.
