AP7361C-33FGE-7

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

The AP7361C-33FGE-7 is a fixed-output linear regulator manufactured by Diodes Incorporated, providing a stable 3.3V output at up to 1A load current. It operates within an input voltage range of 2.2V to 6.0V and features a typical dropout voltage of 360mV at full load. The device incorporates an enable pin for power management and maintains a low quiescent current of approximately 60µA. Built-in protections include thermal shutdown and fold-back short circuit protection. It is housed in a U-DFN3030-8 (Type E) package.

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

Verify the specific suffix FGE corresponds to the U-DFN3030-8 package type when sourcing. Confirm that the -33 designation matches the required 3.3V fixed output voltage. Ensure compatibility with RoHS 3 and halogen-free requirements if mandated by your assembly specifications. Cross-reference the datasheet revision to confirm any updates to electrical characteristics or marking information.

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

Select this component when a compact footprint is required alongside high current capability. The U-DFN3030-8 package offers efficient thermal dissipation for space-constrained designs. Consider the 60µA quiescent current for battery-operated systems where standby power consumption is critical. Verify that the input voltage remains within the 2.2V to 6.0V range during all operating conditions.

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

This part belongs to the AP7361C family of 1A low dropout regulators from Diodes Incorporated. The series includes both adjustable and fixed output variants across multiple packages such as SOT223, TO252, and SO-8EP. The AP7361C-33FGE-7 specifically utilizes the flat DFN package for surface mount applications requiring minimal board space.

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

Direct replacements within the same family include AP7361C-33SP-13 (SO-8EP package) or AP7361C-33ER-13 (SOT223 package). These alternatives share identical electrical specifications but differ in physical dimensions and thermal characteristics. Verify pinout compatibility and PCB layout adjustments before substitution.
