AP7366-28W5-7

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

The Diodes Incorporated AP7366-28W5-7 is a fixed-output low-dropout linear regulator providing 2.8V at up to 600mA output current. It operates within an input voltage range of 2.2V to 6V and maintains a typical quiescent current of 60µA. The device features a dropout voltage of 230mV (typical) at full load, with a maximum of 350mV. It includes built-in current-limit and thermal-shutdown protection circuits. The component is housed in a SOT-25-5 package and supports an ambient operating temperature range from -40°C to +85°C.

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

Verify the specific suffix W5 corresponds to the SOT-25 package and 28 indicates the 2.8V fixed output. Confirm RoHS compliance status through official manufacturer documentation. Check for any discontinuation notices as the datasheet marks this series as not recommended for new design. Ensure EN pin logic levels match system requirements.

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

Select this regulator when a stable 2.8V rail is required with high current capability up to 600mA. Consider the 2.2V minimum input voltage constraint for battery applications. Evaluate thermal dissipation based on the junction-to-ambient resistance of the SOT-25 package. Verify that the 1µF ceramic output capacitor requirement aligns with board space constraints.

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

This component belongs to the AP7366 family of low-dropout regulators manufactured by Diodes Incorporated. The family offers both adjustable and fixed output options in SOT-25 and U-DFN2020-6 packages. The AP7366-28W5-7 specifically denotes the fixed 2.8V variant in the SOT-25 surface-mount package.

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

The datasheet explicitly recommends using the AP7366EA for new designs instead of the AP7366 series.
