Overview
The AP7312-3333W6-7 is a dual-output low dropout linear regulator manufactured by Diodes Incorporated. It provides two fixed positive output voltages of 3.3V each, with a maximum 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 a 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 surface-mount package and supports an operating temperature range from -40°C to +85°C.
Feature Summary
- Dual-channel architecture with independent enable control for each output
- Low quiescent current consumption for battery-powered efficiency
- Integrated protection against overcurrent, short circuit, and thermal overload
- Stable operation with small ceramic output capacitors
Applications
- Cellular phones and mobile communication devices
- Smartphones and personal digital assistants (PDAs)
- Portable media players such as MP3/MP4 devices
- Bluetooth headset power management
Procurement Notes
Verify the specific suffix W6-7 confirms the SOT-26 package and 3.3V/3.3V output configuration. Confirm RoHS compliance and lead-free finish status with the manufacturer or authorized distributor. Check for any recent product change notifications regarding pinout or electrical characteristics before finalizing procurement.
Selection Notes
Select this component when two separate 3.3V rails are required from a single input source between 2V and 6V. Ensure the load current does not exceed 150mA per channel. Verify that the PCB layout accommodates the SOT-26 footprint and that thermal dissipation requirements are met under maximum load conditions.
Part Context
This part belongs to the AP7312 family of dual LDO regulators designed for portable electronics. It shares core specifications with variants offering different output voltage combinations, such as 1.2V/3.3V or 1.5V/3.3V, while maintaining the same 150mA current capability and low IQ profile.
Replacement Considerations
Check for other AP7312 variants with identical 3.3V outputs but different packages if space constraints differ. Verify compatibility with alternative dual LDOs offering similar current ratings and PSRR values.
