ADP3156JR-1.8-REEL

Special Purpose Regulators Overview

The ADP3156JR-1.8-REEL is a dual synchronous buck switching regulator manufactured by Analog Devices Inc., housed in a 16-SOIC package. It provides a fixed 1.8V output voltage with an input range of 3V to 5V. The device integrates two independent power supplies designed for high efficiency and low noise performance, suitable for powering sensitive digital loads in compact surface-mount applications.

Special Purpose Regulators Feature Summary

• Dual synchronous buck architecture for independent power rail generation
• Fixed 1.8V output configuration ensuring stable voltage delivery
• Optimized for high efficiency and low noise operation

Special Purpose Regulators Applications

• Powering dual-core or multi-voltage digital processors
• Embedded systems requiring isolated 1.8V logic rails
• Portable electronics with strict space constraints

Special Purpose Regulators Procurement Notes

Verify the specific suffix 'REEL' indicates tape-and-reel packaging when ordering. Confirm the '1.8' designation matches the required fixed output voltage for your design. Ensure the 16-SOIC footprint aligns with your PCB layout specifications before finalizing procurement.

Special Purpose Regulators Selection Notes

Select this component when a fixed 1.8V output is required without external feedback resistor adjustments. The dual-channel design reduces board space compared to using two separate single regulators. Verify that the 3V-5V input range covers your system's supply variations.

Special Purpose Regulators Part Context

This part belongs to the ADP3156 family of dual synchronous buck controllers from Analog Devices. The JR-1.8 variant specifically denotes the fixed 1.8V output version in a 16-pin SOIC package. It serves as a specialized PMIC solution for applications needing two regulated rails from a single IC.

Special Purpose Regulators Replacement Considerations

Check Analog Devices documentation for pin-compatible alternatives within the ADP315x series. Verify if other output voltage variants (e.g., ADP3156JR-2.5) fit if voltage flexibility is needed. Cross-reference thermal performance and current ratings with potential substitutes.
