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

Verify that the specific suffix SP corresponds to the SO-8EP package configuration required for your PCB layout. Confirm that the -13 packing suffix matches your manufacturing equipment's tape and reel specifications. Ensure the component meets RoHS 3 compliance requirements for your target market regulations before finalizing procurement orders.

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

Select this part when a wide input voltage range up to 45V is necessary alongside a fixed 1.8V output. The SO-8EP package offers improved thermal dissipation compared to smaller packages. Consider the 2.1µA quiescent current for battery-powered designs. Verify that the 300mA continuous current capability aligns with the peak load demands of the downstream circuitry.

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

This component belongs to the AP7375Q series of automotive-compliant ULDO regulators. The series includes variants with different fixed output voltages such as 3.0V, 3.3V, and 5.0V.
