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

Verify the specific suffix B2 corresponds to the TO-92-3 through-hole package configuration when sourcing. Confirm RoHS compliance status as indicated in official datasheets. Ensure the ordering part number matches the exact voltage and package requirements for your design. Check for any recent product change notices regarding packaging or material composition updates from ABLIC.

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

Select this component when a fixed 3.0 V output is required with minimal quiescent current draw. The TO-92-3 package is suitable for through-hole mounting applications where space constraints are less critical than surface-mount alternatives. Consider the 50 mA output limit and ensure the thermal dissipation capabilities of the package meet the system's power loss requirements under maximum load conditions.
