The LDK220PU33R from STMicroelectronics is a low dropout linear regulator delivering a fixed 3.3V output with up to 200mA current. Its 90 µA quiescent current and 0.35V dropout at full load make it suitable for battery-operated and power-sensitive applications. The compact 6-DFN package supports space-constrained designs.
- Extended Battery Life: Ultra-low 90 µA quiescent current reduces standby power consumption.
- Stable Output: 55dB PSRR at 120Hz filters ripple for clean power delivery.
- Space-Saving: 6-DFN (1.2x1.3) package fits tight PCB layouts.
- Reliable Performance: 0.35V dropout at 200mA ensures efficient operation near battery end-of-life.
