AP7312-1218FM-7

Overview

The AP7312-1218FM-7 is a dual fixed output low dropout linear regulator manufactured by Diodes Incorporated. It provides two independent regulated outputs of 1.2V and 1.8V, 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 utilizes a DFN2018-6 package and includes integrated protection mechanisms such as current limit, short circuit, and thermal shutdown.

Feature Summary

Dual channel architecture with independent enable pins for individual channel control
Integrated protection against overcurrent, short circuits, and overheating
Fast transient response capability suitable for rapidly changing load conditions
Low dropout performance ensuring stable regulation under varying input voltages

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 tape & reel packaging configuration. Ensure compatibility with the required PCB footprint dimensions and pad layout specifications provided in the manufacturer's application notes. Confirm that the component meets RoHS compliance standards for your manufacturing process.

Selection Notes

Select this component when a dual rail supply is required within a 2V to 6V input window. The 1.2V and 1.8V fixed outputs eliminate the need for external resistive dividers. Consider the DFN2018-6 package for its thermal dissipation capabilities relative to the SOT26 alternative. Verify that the system load does not exceed the 150mA per channel limit.

Part Context

This part belongs to the AP7312 family of dual LDO regulators designed for mobile and handheld devices. It serves as a power management solution for baseband circuits and RF modules requiring fast transient response. The datasheet indicates it is not recommended for new designs, suggesting newer alternatives may be available.
