The SCT71401F33TYFR is a fixed 5V LDO regulator from SCT, capable of sourcing 150mA. Housed in a SOT-89 package, it offers improved power dissipation for higher ambient temperature applications. With a typical input of 1.2V and dropout of 0.643V at full load, it maintains regulation in low-headroom designs. The PSRR of 52dB at 100kHz makes it suitable for noise-sensitive analog circuits.
- Enhanced Thermal Performance: SOT-89 package dissipates heat more effectively than smaller SOT-23 variants.
- Stable 5V Output: Fixed output eliminates external components, reducing BOM cost.
- High PSRR: 52dB at 100kHz rejects switching noise for clean power delivery.
- Low Dropout: 0.643V dropout supports efficient operation from 1.2V input.
