The UM1560P-18 is a fixed 1.8V low dropout linear regulator from Union Semiconductor, delivering up to 300mA. Its ultra-low 3.5 µA quiescent current and 0.3V dropout at 200mA make it ideal for battery-powered devices. The SOT-343 package saves board space while providing stable output with 56dB PSRR at 100Hz.
- Extended Battery Life: Ultra-low 3.5 µA quiescent current minimizes standby power draw, ideal for portable electronics.
- High Efficiency at Low Dropout: 0.3V dropout at 200mA allows operation close to the output voltage, reducing power dissipation.
- Compact Footprint: SOT-343 package is ideal for space-constrained designs without sacrificing performance.
- Clean Output: 56dB to 42dB PSRR (100Hz-1kHz) effectively rejects input noise, ensuring stable voltage for sensitive loads.
