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

Verify the specific suffix and packaging configuration against official datasheets before procurement, as ordering codes may vary. Confirm RoHS compliance status and environmental declarations directly with the manufacturer or authorized distributors. Ensure that the HRP-5 package dimensions match your PCB footprint requirements precisely. Check for any updated automotive qualification certifications if the application demands strict functional safety standards.

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

Select this component when a fixed 3.3V rail is required with high input voltage tolerance up to 36V. The low quiescent current makes it suitable for battery-powered applications where standby consumption must be minimized. Consider the thermal dissipation capabilities of the HRP-5 package under maximum load conditions to ensure junction temperatures remain within safe operational limits across the specified temperature range.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the BD3573 series of LDO regulators designed for robust performance in noisy environments. It is distinct from adjustable variants like the BD3575 series due to its fixed output configuration. The HRP-5 package offers a compact solution for space-constrained designs while maintaining adequate heat dissipation characteristics for moderate current loads.
