The SCT71401F50TWDR is a fixed 5V low dropout linear regulator from SCT, delivering up to 150mA of output current. With a typical input voltage of 1.2V and a low dropout voltage of 0.643V at full load, it ensures efficient regulation in battery-powered applications. The SOT-23-5 package offers a compact solution for space-constrained designs, while the high PSRR (52dB at 100kHz) provides excellent noise rejection for sensitive loads.
- High Noise Rejection: PSRR of 52dB at 100kHz ensures clean output for RF and analog circuits.
- Low Dropout: 0.643V dropout at 150mA maximizes efficiency in low-voltage systems.
- Compact Package: SOT-23-5 footprint saves PCB space for miniaturized designs.
- Fixed 5V Output: Simplifies design with no external resistor divider needed.
Battery-Powered Devices
Ideal for portable electronics where a stable 5V rail is needed from a 1.2V source, ensuring consistent performance as the battery discharges.
Sensor Power Supply
Provides clean, low-noise 5V power to analog sensors, leveraging the high PSRR (52dB at 100kHz) to reject high-frequency noise from switching converters.
