Overview
The AP7312-1525W6-7 is a dual-channel low dropout linear regulator manufactured by Diodes Incorporated. It provides fixed output voltages of 1.5V and 2.5V with a continuous output current of 150mA per channel. The device operates within an input voltage range of 2V to 6V and features a typical quiescent current of 60µA. It offers high power supply rejection ratio (PSRR) of 65dB at 1kHz and includes independent enable pins for each channel. The component is housed in a SOT-26 package and supports operation temperatures from -40°C to +85°C.
Feature Summary
- Dual-channel architecture with independent enable controls for flexible power management
- Low quiescent current consumption suitable for battery-powered applications
- Integrated protection mechanisms including current limit, thermal shutdown, and short circuit protection
Applications
- Cellular phones and smart phones
- Personal digital assistants (PDAs)
- MP3/MP4 media players
- Bluetooth headsets
- General low-power electronic devices
Procurement Notes
Verify the specific suffix W6-7 to confirm the SOT-26 package type and RoHS compliance status. Ensure the ordering quantity aligns with manufacturer reel specifications. Confirm availability through authorized distributors as lead times may vary. Cross-reference the datasheet for exact pinout configurations and thermal characteristics before finalizing procurement decisions.
Selection Notes
Select this component when dual isolated rails are required from a single input source. The 150mA rating suits moderate load requirements. Verify that the input voltage remains within the 2V to 6V window. Consider the SOT-26 footprint constraints during PCB layout. Ensure the application does not exceed the maximum junction temperature limits under expected thermal conditions.
Part Context
This part belongs to the AP7312 series of dual LDO regulators. It shares core electrical characteristics with variants offering different output voltage combinations, such as 1.2V/3.3V or 3.3V/3.3V. The primary distinction lies in the fixed output voltage pair and the physical package configuration. All variants maintain similar quiescent current and protection feature sets.
Replacement Considerations
Compatible substitutes include other AP7312 variants with matching output voltages or higher current ratings. Verify pin compatibility and package dimensions before substitution. Ensure replacement parts meet the same environmental and regulatory standards.
