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

Verify the specific -AQ suffix status, as documentation indicates this variant is currently undergoing AEC-Q100 qualification rather than being fully compliant. Confirm that the standard datasheet parameters apply to the qualified version if required for automotive use. Ensure compatibility with the SOT-89 footprint and check for any updates regarding the final qualification outcome before finalizing procurement specifications.

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

Select this component for designs requiring a stable 5V rail with up to 100mA load capacity in a compact SOT-89 package. Consider the 1.7V dropout voltage when determining the minimum required input voltage. Verify that the thermal dissipation capabilities are sufficient for the expected power loss under maximum load conditions. Ensure the application environment falls within the specified commercial/industrial temperature range.

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

This part belongs to the DI78LxxUAB series of positive fixed voltage regulators manufactured by Diotec Semiconductor. The series offers various fixed output voltages ranging from 3.3V to 24V. The -AQ suffix denotes a specific grade intended for automotive qualification processes, distinguishing it from the standard commercial versions available in other packages like SO-8 or TO-92.
