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

Verify the specific suffix 'DBVR' corresponds to the SOT-23-5 package and tape-and-reel shipping format. Confirm the '05' designation matches the required 5.0V fixed output voltage. Ensure the component meets RoHS compliance standards for your manufacturing process. Cross-reference the datasheet revision date to confirm availability of the latest electrical characteristics.

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

Select this regulator when a wide input voltage range up to 40V is required alongside minimal standby power consumption. It is suitable for applications where space is constrained due to its small SOT-23 footprint. Consider the dropout voltage characteristics at full load when designing for low input-to-output differentials. Ensure the output capacitor value remains within the specified 1μF to 47μF range for guaranteed stability.
