Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the complete part number including the suffix -E2 for RoHS compliance and long-term supply status. Confirm the specific fixed output voltage variant required, as the base model may denote a series. Ensure the TO-252-3 package matches the target PCB footprint. Check official documentation for automotive usage restrictions, as this standard-grade product is not recommended for vehicle equipment.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a 1A fixed output LDO with high withstand voltage is required in a compact SMD package. The low dropout characteristic makes it suitable for applications where input-output voltage differential is limited. Consider the 0.5mA quiescent current for power-sensitive designs. Verify that the required fixed output voltage aligns with available variants within the BDxxFC0 series.
