AP7311-12WG-7

Overview

The AP7311-12WG-7 is a fixed-output low dropout linear regulator manufactured by Diodes Incorporated. It provides a stable 1.2V 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 65µA across the full load range. It includes built-in current limit, short circuit, and thermal shutdown protections. The component is housed in a SOT-25 package and supports an ambient operating temperature range from -40°C to +85°C.

Feature Summary

• Provides fast transient response suitable for rapidly changing loads
• Includes active high enable pin for power management control
• Offers comprehensive protection against overcurrent and overheating

Applications

• Portable devices requiring efficient power regulation
• Battery powered equipment
• Cellular phones and baseband circuits

Procurement Notes

Verify that the specific part number matches the required fixed 1.2V output configuration. Confirm the package type is SOT-25 and ensure compliance with RoHS standards if applicable. Check datasheet specifications for input voltage and load current requirements before integration.

Selection Notes

Select this component when a fixed 1.2V rail is needed with moderate current demands up to 150mA. Consider its low quiescent current for battery life extension. Ensure the input voltage remains within the 2V to 6V range and verify PCB layout guidelines for stability with ceramic capacitors.

Part Context

This part belongs to the AP7311 series of low dropout regulators designed for portable electronics. The series offers both adjustable and fixed output options. The AP7311-12WG-7 specifically denotes the 1.2V fixed version in a green molding compound SOT-25 package supplied in tape and reel format.

Replacement Considerations

AP7311-10WG-7 (1.0V), AP7311-15WG-7 (1.5V). Verify output voltage compatibility before substitution.
