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

Verify the specific suffix V5T2 corresponds to the TO-252-5S(A) package and tape packing format. Confirm AEC-Q100 qualification status directly with ABLIC sales representatives as detailed specifications are not fully listed in public datasheets. Ensure application conditions do not exceed absolute maximum ratings regarding junction temperature and power dissipation.

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

Select this component when a fixed 10.5 V output is required for automotive environments. The D-type logic requires a minimum 2.0 V input on the ON/OFF pin to activate. Verify that the input capacitor meets the 1.0 μF minimum requirement for stability. Consider thermal resistance values based on the PCB layout to prevent triggering the thermal shutdown circuit during high load conditions.
