The UM1560S-42 is a high-performance low dropout linear regulator from Union Semiconductor, delivering a fixed 4.2V output with up to 300mA of current. Its ultra-low 3.5 µA quiescent current makes it an excellent choice for battery-powered devices, while the 0.3V dropout at 200mA ensures efficient operation. Housed in a compact SOT-23-5 package, this LDO provides clean, stable power with good ripple rejection for sensitive electronics.
- Extended Battery Life: Ultra-low 3.5 µA quiescent current minimizes standby power consumption, ideal for portable and IoT devices.
- High Efficiency at Low Dropout: 0.3V dropout at 200mA allows operation close to the output voltage, reducing power dissipation.
- Stable Output: PSRR of 56dB to 42dB (100Hz-1kHz) filters supply noise, ensuring clean power for sensitive analog circuits.
- Compact Footprint: SOT-23-5 package saves board space for space-constrained designs.
