AP7365-39YG-13

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

The AP7365-39YG-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 a SOT89 (Y Package) surface-mount package. Key electrical characteristics include a line regulation of 0.02%/V, load regulation of 1%, and a power supply rejection ratio of 65dB at 1kHz. The unit supports an ambient temperature range from -40°C to +85°C.

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

Verify the specific ordering suffix 'YG-13' corresponds to the SOT89 package and tape & reel packaging configuration. Confirm that the component meets RoHS compliance and halogen-free requirements as defined by the manufacturer. Ensure the application environment remains within the specified operating temperature limits to maintain performance stability.

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

Select this part when a fixed 3.9V rail is required with high current capability in a compact footprint. The low quiescent current makes it suitable for battery-powered systems where standby consumption is critical. Verify that the input voltage never exceeds the maximum rating of 6V during normal operation or transients.

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

This component belongs to the AP7365 series of 600mA low dropout regulators. The series offers both adjustable and fixed output options ranging from 0.8V to 3.9V. The AP7365 is designed for portable applications requiring fast transient response and low noise. Note that the datasheet indicates this device is not recommended for new designs; the AP7366 is suggested as an alternative.

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

The AP7366 is explicitly recommended by the manufacturer as the replacement for new designs due to the AP7365 being marked as not recommended for new design.
