Overview
The AP7312-1830W6-7 is a dual-output low dropout linear regulator manufactured by Diodes Incorporated. It provides fixed output voltages of 1.8 V and 3.0 V, each capable of delivering up to 150 mA. The device operates within an input voltage range of 2 V to 6 V and maintains a typical quiescent current of 60 µA. It features high power supply rejection ratio (PSRR) of 65 dB at 1 kHz and ensures stability with low equivalent series resistance ceramic capacitors. The unit supports independent channel enable control and includes comprehensive protection mechanisms.
Feature Summary
- Dual-channel architecture providing independent 1.8 V and 3.0 V outputs for multi-rail system requirements
- Integrated enable pins allow independent control of each regulator channel via logic high signals
- Built-in thermal shutdown and current limit circuitry protect the IC against fault conditions
Applications
- Cellular phones and smart phones requiring multiple stable voltage rails
- Personal digital assistants and portable media players
- Bluetooth headsets and other low-power wireless communication devices
Procurement Notes
Verify the specific suffix W6-7 confirms the SOT-26 package and RoHS compliance status before ordering. Confirm that the 1.8 V and 3.0 V output combination matches your design requirements exactly. Ensure compatibility with standard surface mount assembly processes for the specified package type.
Selection Notes
Select this component when two distinct fixed voltages are needed from a single package to save board space. The 150 mA output current per channel suits moderate load applications. Verify that the input voltage remains within the 2 V to 6 V range for proper regulation. Consider the 60 µA quiescent current impact on overall battery life in portable designs.
Part Context
This part belongs to the AP7312 family of dual LDO regulators from Diodes Incorporated. The family offers various fixed output voltage combinations in SOT-26 and DFN2018-6 packages. These regulators are designed for portable electronics where size and efficiency are critical constraints.
Replacement Considerations
Check datasheets for other AP7312 variants with different output voltage pairs. Verify pinout compatibility if substituting with similar dual LDOs from other manufacturers.
