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

Verify the specific ordering suffix FDC confirms the U-DFN2020-6 (Type C) package configuration. Confirm that the required output voltage matches the 3.6V specification. Ensure application requirements align with the absolute maximum ratings, particularly regarding input voltage limits and junction temperature thresholds. Validate compliance with RoHS and halogen-free standards if mandated by project specifications.

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

Select this component when a wide input voltage range up to 60V is required alongside low standby current consumption. The U-DFN2020-6 package offers a compact footprint suitable for space-constrained designs. Consider the thermal resistance characteristics of the exposed pad for effective heat dissipation under heavy load conditions. Verify that the required output capacitance meets stability criteria for the chosen operating environment.
