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

Verify the specific suffix 'MP' corresponds to the MSOP-8EP package and '-13' indicates tape and reel packaging. Confirm the 'AQ' designation ensures the inclusion of the Power-Good function and automotive compliance. Cross-reference the full part number against the manufacturer's official ordering guide to ensure correct output voltage and package type selection.

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

Select this component when a fixed 5V rail is required with high input voltage tolerance up to 42V. The integrated power-good signal simplifies system sequencing compared to the standard Q version. Ensure the application requires the specific MSOP-8EP footprint and that the 300mA load capacity meets the design specifications.

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 series offers both adjustable and fixed output options in multiple packages.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ

What is the function of the PG pin on the AP7583AQ?

The PG pin acts as an open-drain output indicating when the output voltage has reached its regulation threshold. It goes high-impedance when VOUT is above the rising threshold and pulls low when VOUT drops below the falling threshold or the device is disabled.

How does the AP7583AQ differ from the AP7583Q?

The primary difference is that the AP7583AQ includes a Power-Good (PG) output pin for status monitoring, whereas the AP7583Q does not have this feature. Both share similar electrical characteristics regarding input voltage, current, and protection functions.
