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

Verify the specific suffix W5 confirms the SOT-25 package variant before ordering. Confirm that the 1.8V output version aligns with system requirements. Check for any recent product change notices or discontinuation alerts from Diodes Incorporated, as availability may vary by region and distributor.

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

Select this component when a fixed 1.8V rail is required with minimal ground current consumption. Ensure the input voltage stays within the 3.5V to 30V operational range. Verify that the load current does not exceed 150mA and that thermal dissipation remains within limits for the SOT-25 package under expected ambient conditions.

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

This part belongs to the AP7383 series of wide-input voltage ULDO regulators. It shares features like thermal shutdown and low dropout characteristics with other variants in the family, such as those offering 3.0V, 3.3V, or 5.0V outputs. The W5 suffix specifically denotes the SOT-25 package configuration.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Other AP7383 variants with different output voltages (e.g., AP7383-30W5-7 for 3.0V) share the same package and pinout but provide different regulated outputs. Direct substitution requires matching the required output voltage level. Consult Diodes Incorporated for automotive-grade alternatives if AEC-Q100 qualification is needed.
