AP7361EA-FGE-7

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

The AP7361EA-FGE-7 is a 1A low dropout linear regulator with enable function, manufactured by Diodes Incorporated. It operates within an input voltage range of 2.2V to 6.0V and provides an adjustable output voltage from 0.8V to 5.0V. The device features a typical quiescent current of 68µA and high power supply rejection ratio of 75dB at 1kHz. It includes built-in current limiting (1.5A), foldback short-circuit protection (400mA), and thermal shutdown at 150°C. The component is housed in a U-DFN3030-8 (Type E) package.

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

Verify the specific ordering suffix FGE corresponds to the U-DFN3030-8 (Type E) package configuration. Confirm that the part number indicates the adjustable output version, as the absence of a voltage code in the suffix denotes this mode. Ensure compliance with RoHS 3 and halogen-free requirements if specified for the target application environment.

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 with a maximum load current of 1A. It is suitable for applications needing low ground current and fast start-up times. Consider the U-DFN3030-8 package for compact designs requiring exposed pad thermal dissipation. Ensure the input voltage remains within the 2.2V to 6.0V operating range.

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

This part belongs to the AP7361EA series of low dropout regulators. The series offers both fixed and adjustable output options across multiple packages including SOT89-5, SOT223, TO252, and SO-8EP. The AP7361EA-FGE-7 specifically utilizes the U-DFN3030-8 package and supports adjustable output via external resistors, distinguishing it from fixed-voltage variants within the same family.

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

What is the function of the ADJ/NC pin on the U-DFN3030-8 package?

For the adjustable output version, the ADJ/NC pin is used to set the output voltage via an external resistor divider connected between the OUT pin and ground.

How does the enable pin operate?

The EN pin is active-high; setting it to a logic-high level turns the regulator on, while pulling it low turns it off. If unused, it should be tied to the IN pin.

What is the thermal shutdown threshold?

Thermal shutdown protection disables the output when the junction temperature rises to approximately +150°C, restoring operation when the temperature drops to approximately +130°C.
