The UM1460Y-33 is a low dropout linear regulator delivering a fixed 3.3V output with up to 250mA of current. Its ultra-low 5 µA quiescent current makes it an excellent choice for battery-operated devices. The SOT-89-5 package provides a compact footprint while the 0.3V dropout at 150mA ensures efficient operation. With 40dB PSRR at 100Hz, it effectively filters power supply noise for sensitive analog and digital circuits.
- Extended Battery Life: Ultra-low 5 µA quiescent current minimizes standby power consumption, ideal for portable devices.
- High Efficiency at Low Dropout: 0.3V dropout at 150mA allows operation close to the output voltage, reducing power dissipation.
- Compact SOT-89-5 Package: Small footprint saves PCB space for space-constrained designs.
- Good Ripple Rejection: 40dB PSRR at 100Hz ensures clean output for noise-sensitive applications.
