Overview
The ADP667AR is a low-dropout linear regulator manufactured by Analog Devices Inc., designed for stable voltage regulation in surface-mount applications. It operates within an input voltage range of 3.5 V to 16.5 V and provides a maximum output current of 250 mA. The device supports both fixed and adjustable output configurations, with the adjustable version offering an output range from 1.3 V to 16 V. It features a reference voltage of 1.28 V and maintains a typical quiescent current of 25 µA. The component is housed in an SOIC-8 package and is rated for operation between -40 °C and +85 °C.
Feature Summary
- Supports both fixed and adjustable output voltage configurations for flexible design integration
- Low quiescent current consumption enhances efficiency in battery-powered systems
- Capable of delivering up to 250 mA load current with low dropout performance
Applications
- Portable electronic devices requiring efficient power management
- Battery-operated equipment needing extended runtime
- General-purpose voltage regulation in industrial control systems
Procurement Notes
Verify the specific suffix (e.g., AR vs. ARZ) against official Analog Devices documentation to confirm lead-free status and RoHS compliance. Confirm availability through authorized distributors as supply may be limited. Ensure the selected package matches the PCB footprint requirements. Validate operating temperature ranges against application environmental conditions before finalizing procurement.
Selection Notes
Select this component when a reliable LDO with adjustable output flexibility is required. Consider the 250 mA current limit and input voltage range suitability for the target circuit. Evaluate thermal dissipation capabilities based on the SOIC-8 package and expected load conditions. Compare quiescent current specifications against system power budget constraints to ensure optimal efficiency.
Part Context
The ADP667 series represents Analog Devices' lineup of low-dropout regulators focusing on stability and efficiency. This specific part belongs to the broader PMIC category, serving as a fundamental power management solution for converting higher input voltages to stable lower levels. It complements other ADI components in mixed-signal and embedded systems.
Replacement Considerations
Consult official Analog Devices substitution guides for verified alternatives. Cross-reference pinouts and electrical parameters such as dropout voltage and current limits when evaluating potential replacements.
