AP7312-1833FM-7

Overview

The AP7312-1833FM-7 is a dual fixed output low dropout linear regulator manufactured by Diodes Incorporated. It provides two independent positive voltage outputs of 1.8V and 3.3V, each capable of delivering up to 150mA. The device operates with an input voltage range from 2V to 6V and features a typical quiescent current of 60µA. It includes integrated current limit, short circuit, and thermal shutdown protections. The component is housed in a DFN2018-6 surface-mount package.

Feature Summary

• Dual independent channels with individual enable pins for power management
• Fast transient response suitable for rapidly changing load conditions
• Integrated protection against overcurrent, short circuits, and overheating
• Stable operation with small ceramic output capacitors

Applications

• Cellular phones
• Smart phones and PDAs
• MP3/MP4 players
• Bluetooth headsets
• Low power portable applications

Procurement Notes

Verify the specific ordering suffix FM-7 confirms the DFN2018-6 package type and 1.8V/3.3V output configuration. Confirm RoHS compliance status and check for any product change notifications regarding leadframe material or bond wire composition before finalizing procurement specifications.

Selection Notes

Select this component when a dual rail supply is required within a 2V to 6V input window. Ensure the application load does not exceed 150mA per channel. Verify that the PCB layout supports the DFN2018-6 package thermal requirements and utilizes at least 1µF ceramic capacitors on both inputs and outputs for stability.

Part Context

This part belongs to the AP7312 family of dual 150mA low dropout regulators. The 'FM' suffix designates the DFN2018-6 package variant, while '1833' specifies the 1.8V and 3.3V fixed output voltages. The datasheet indicates this series is not recommended for new designs, suggesting consideration of newer alternatives like the AP7345D.
