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

Verify the specific suffix MP indicates MSOP-8EP packaging and 13 confirms tape and reel quantity. Confirm AQ designation ensures inclusion of the power-good function compared to standard Q versions. Ensure AEC-Q100 qualification aligns with target automotive reliability standards before finalizing procurement specifications.

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

Select this component when a stable 3.3V rail is required from high-voltage automotive bus lines up to 42V. The integrated power-good pin facilitates system sequencing logic. Consider the MSOP-8EP package for its exposed pad thermal dissipation capabilities in compact PCB layouts requiring surface mount assembly.

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

This part belongs to the AP7583Q/AQ series of wide-input-voltage LDO regulators designed for automotive environments. The 'AQ' variant specifically adds a power-good output feature not present in the base 'Q' model. The '33' suffix denotes the fixed 3.3V output voltage setting.

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

AP7583Q-33MP-13 serves as a functional substitute lacking the power-good pin. Other package variants like AP7583AQ-33FDZW-7 offer identical electrical performance in W-DFN2020-6 form factors.
