AP7311-18SNG-7

Overview

The AP7311-18SNG-7 is a fixed-output low dropout linear regulator manufactured by Diodes Incorporated. It provides a stable 1.8V output with a maximum load current of 150mA. The device operates within an input voltage range of 2V to 6V and features a typical quiescent current of 85µA. It is housed in a compact SOT-25 surface-mount package, suitable for space-constrained portable electronics applications requiring efficient power management.

Feature Summary

• Fixed 1.8V output voltage configuration
• Low quiescent current consumption
• Compact SOT-25 surface-mount packaging

Applications

• Portable battery-powered devices
• Consumer electronics power supplies
• Embedded system voltage regulation

Procurement Notes

Verify the specific suffix 'SNG' against the manufacturer's latest datasheet to confirm pinout and thermal characteristics. Ensure compatibility with the target PCB footprint for the SOT-25 package. Cross-reference ordering information with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a fixed 1.8V rail is required with minimal external circuitry. Consider the 150mA current limit and 85µA standby current for battery life optimization. Verify that the input voltage remains within the 2V to 6V operational window under all load conditions.

Part Context

This part belongs to the AP7311 series of low dropout regulators from Diodes Incorporated. The series offers various fixed output voltages and adjustable options in small packages. The AP7311-18SNG-7 specifically denotes the 1.8V fixed version in the SOT-25 package.

Replacement Considerations

Check for direct substitutes such as other AP7311 variants with different output voltages if voltage adjustment is needed. Verify pin-to-pin compatibility with alternative LDOs from other manufacturers offering similar 150mA current ratings and SOT-25 packaging.
