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

Verify that the ordering suffix FGE corresponds to the U-DFN3030-8 (Type E) package configuration. Confirm the ADJ designation indicates the adjustable output variant rather than a fixed voltage option. Ensure compliance with RoHS 3 and REACH standards as specified in the manufacturer documentation.

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

Select this component when an adjustable output voltage between 0.8V and 5.0V is required. The U-DFN3030-8 package provides a compact footprint suitable for space-constrained designs. Verify that the external resistor divider values maintain stability and meet the internal reference requirements.

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

This part belongs to the AP7361C series of low dropout regulators. The series offers both fixed and adjustable output options across multiple package types including SOT89-5, SOT223, and SO-8EP. The AP7361C-FGE-7 specifically utilizes the U-DFN3030-8 package for high-density surface mount applications.

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

AP7361C-XXFGE-7 variants with different output codes (e.g., 18 for 1.8V) share the same package but provide fixed voltages. Other packages like SOT89-5 or SO-8EP offer equivalent electrical characteristics but require layout adjustments due to physical differences.

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

How is the output voltage adjusted?

The output voltage is set using an external resistor divider connected to the ADJ pin, allowing adjustment from 0.8V to 5.0V based on the internal 0.8V reference.

What happens during a short circuit condition?

Short circuit protection triggers and clamps the output current to approximately 400mA. Full current is restored once the output voltage exceeds 15% of its nominal value.
