The LDK220M36R from STMicroelectronics is a low dropout linear regulator delivering a fixed 3.6V output with up to 200mA of current. Its low quiescent current of 90 µA and dropout voltage of 0.35V make it an efficient choice for battery-operated and noise-sensitive applications. Housed in a compact SOT-23-5 package, it offers reliable performance with good power supply rejection.
- Extended Battery Life: Ultra-low 90 µA quiescent current minimizes standby power consumption.
- High Efficiency at Low Dropout: 0.35V dropout at 200mA allows operation from a 3.8V rail with minimal power loss.
- Clean Output: PSRR of 55dB to 50dB (120Hz-10kHz) reduces ripple and noise for sensitive loads.
- Compact Footprint: SOT-23-5 package saves board space in portable designs.
Battery-Powered Devices
The low 90 µA quiescent current and 200mA output make it ideal for extending battery life in portable electronics like wearables and IoT sensors.
