The LDK220PU27R from STMicroelectronics is a low dropout linear regulator delivering a fixed 2.7V output with up to 200mA current. Its 90µA quiescent current and 0.35V dropout at full load make it efficient for battery-operated devices. The compact 6-DFN package (1.2x1.3mm) saves board space, while PSRR of 55dB at 120Hz ensures clean power for sensitive analog circuits.
- Extended Battery Life: Ultra-low 90µA quiescent current minimizes standby power consumption in portable devices.
- Space-Saving Design: The 1.2x1.3mm DFN package fits high-density PCB layouts for wearables and IoT modules.
- Stable Output: 55dB PSRR at 120Hz effectively rejects low-frequency noise from power supplies.
- Low Dropout: 0.35V dropout at 200mA allows operation from nearly depleted batteries.
