AP7366-15W5-7

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

The AP7366-15W5-7 is a fixed-output low-dropout linear regulator manufactured by Diodes Incorporated. It provides a stable 1.5V output with a maximum continuous current of 600mA. The device operates within an input voltage range of 2.2V to 6V and features a typical quiescent current of 60µA. Key electrical parameters include a dropout voltage of 450mV (max) at 300mA load, line regulation of 0.01%/V, and load regulation of 1%. It offers high power supply rejection ratio (PSRR) of 75dB at 1kHz and fast transient response. The component is housed in a SOT-25-5 surface-mount package.

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

Verify the specific ordering suffix 'W5' confirms the SOT-25 package type and '15' indicates the fixed 1.5V output voltage. Confirm RoHS compliance status and check for any automotive qualification requirements if applicable to the target system. Ensure the datasheet revision matches the design specifications before finalizing procurement orders.

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

Select this component when a fixed 1.5V rail is required with up to 600mA load capability. Consider the 2.2V minimum input voltage constraint against the available supply rails. Evaluate the thermal performance based on the junction-to-ambient resistance of the SOT-25 package under expected ambient temperature conditions to ensure reliable operation without triggering thermal shutdown.

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

This part belongs to the AP7366 family of 600mA low-quiescent current linear regulators. The family includes both adjustable and fixed output variants across multiple packages including U-DFN2020-6. The AP7366-15W5-7 specifically denotes the fixed 1.5V version in the SOT-25 package. The series is designed for portable devices requiring efficient power management.

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

The datasheet explicitly recommends using AP7366EA instead of the AP7366 series for new designs. Verify if the AP7366EA variant meets all electrical and mechanical requirements as a direct replacement.
