The SCT71401F50TYDR is a fixed 5V low dropout linear regulator from SCT, delivering up to 150mA of output current. Housed in a compact SOT-23-3 package, it features a low dropout voltage of 0.643V at full load, making it efficient for battery-operated systems. With excellent PSRR performance across a wide frequency range, it ensures clean power delivery for sensitive analog and digital circuits.
- Stable 5V Output: Fixed 5V regulation simplifies design and ensures compatibility with standard logic and sensor rails.
- Low Dropout (0.643V @ 150mA): Maximizes battery life by allowing operation close to the output voltage.
- High PSRR (52dB @ 100kHz): Effectively filters high-frequency noise, ideal for RF and precision analog applications.
- Compact SOT-23-3 Package: Saves board space for space-constrained portable designs.
Battery-Powered IoT Sensors
The 5V fixed output and low dropout of 0.643V at 150mA make it ideal for regulating battery voltage in IoT nodes, ensuring stable operation as the battery discharges.
Portable Medical Devices
With a compact SOT-23-3 package and 150mA capability, it suits wearable monitors and glucose meters requiring a clean 5V rail from a single-cell supply.
Industrial Control Modules
Its PSRR of 52dB at 100kHz helps reject high-frequency switching noise, making it suitable for powering sensors and microcontrollers in industrial environments.
Automotive Infotainment
The 5V output can power display drivers or audio codecs, while the low dropout ensures consistent performance under load transients.
Smart Home Hubs
Use it to regulate 5V for communication modules (Wi-Fi/Bluetooth) where input voltage may sag; the 150mA current is sufficient for low-power RF transceivers.
LED Driver Reference
