FAQ

Q: What capacitors are required for the LD1117S33TR?
A: A 10µF tantalum or ceramic capacitor on the output is recommended for stability. The LD1117 is stable with ESR from 0.3Ω to 22Ω. For ceramic output capacitors, ensure the ESR is within this range or add a small series resistor.

Q: Can the LD1117S33TR be powered directly from a LiPo battery?
A: Yes, for up to 4S LiPo (16.8V max). The input voltage rating is 15V absolute maximum, so for 4S operation use a pre-regulator or ensure your fully-charged 4S pack is within tolerance. For 6S, use a buck converter before the LDO.
