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

Verify that the ordering suffix matches the required package type and packing quantity. Confirm the specific output voltage code aligns with design requirements. Ensure compatibility with the intended PCB footprint for the U-DFN2020-6 package. Check for any automotive qualification requirements if applicable to the end application.

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

Select this component when a fixed 1.0V rail is needed with high noise rejection capabilities. Consider the U-DFN2020-6 package for space-constrained designs. Evaluate the quiescent current and dropout voltage characteristics against the specific load and input voltage conditions of the target application.

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

This part belongs to the AP7347E series of 500mA high PSRR low noise LDOs. The series includes both fixed and adjustable output versions available in U-DFN2020-6 and V-DFN3030-8 packages. The 'E' designation distinguishes it from other variants like the AP7347DQ which may lack the power-good feature.

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

AP7347E-10FDCWR-7R offers the same electrical specifications but utilizes the FDCWR package variant.

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

What is the function of the PG pin?

The Power-Good (PG) pin is an open-drain output that indicates when the output voltage has reached its valid regulation threshold.

How does the device handle short circuits?

It incorporates fold-back short-circuit protection that clamps the output current to approximately 180mA to prevent overheating.
