AP7365-39EG-13

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

The AP7365-39EG-13 is a fixed-output low dropout linear regulator manufactured by Diodes Incorporated. It provides a stable 3.9V output with a maximum continuous current of 600mA. The device operates within an input voltage range of 2V to 6V and features a typical quiescent current of 35µA. It utilizes the SOT-223 package and supports surface mount installation. Key electrical characteristics include a dropout voltage of 300mV at full load, a power supply rejection ratio of 65dB at 1kHz, and a fast start-up time of 200µs. The unit functions reliably across an ambient temperature range of -40°C to +85°C.

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

Verify that the specific part number matches the required output voltage and package type before ordering. Confirm compliance with RoHS directives and halogen-free requirements if mandated by project specifications. Ensure the supplier source is authorized to guarantee component authenticity and traceability. Review the datasheet for any recent product change notifications or obsolescence warnings prior to final procurement decisions.

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

Select this component when a fixed 3.9V rail is required from a 2V to 6V input source. The SOT-223 package offers higher thermal dissipation capabilities compared to smaller footprints. Verify that the application load does not exceed the 600mA rating and that the input-to-output differential allows for proper regulation without triggering thermal shutdown under worst-case ambient temperatures.

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

This device belongs to the AP7365 family of low dropout regulators designed for portable and battery-powered applications. The family includes adjustable and fixed output variants available in multiple packages such as SOT25, U-DFN2020-6, SOT89, and SOT223. The AP7365 series emphasizes low ground current and fast transient response to support dynamic load changes common in modern digital circuits.

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

The manufacturer recommends using the AP7366 for new designs instead of the AP7365. Verify compatibility regarding pinout, package dimensions, and electrical parameters if substituting with other LDO families.
