ADP5304ACPZ-1-R7

Overview

The ADP5304ACPZ-1-R7 is a single-output step-down switching regulator from Analog Devices, housed in a 10-pin LFCSP package. It operates with an input voltage range of 2.15 V to 6.5 V and provides a programmable output voltage between 800 mV and 5 V. The device supports a maximum output current of 50 mA (with 500 mA peak capability) and features a fixed switching frequency of 2 MHz. Key electrical specifications include a quiescent current of 260 nA and an operating temperature range from -40°C to +125°C.

Feature Summary

• Integrates a synchronous buck converter topology for high efficiency within a compact surface-mount footprint.
• Features ultralow power consumption with shutdown mode to extend battery life in portable applications.
• Includes internal soft-start circuitry to limit inrush current during startup sequences.

Applications

• Portable consumer electronics requiring efficient power management
• Battery-powered IoT sensor nodes
• Embedded systems with strict size constraints

Procurement Notes

Verify the specific suffix 'R7' corresponds to the required reel packaging configuration for your assembly line. Confirm that the LFCSP-10 thermal pad requirements match your PCB layout guidelines. Ensure compatibility with the 2.15 V minimum input voltage constraint for your system's power source.

Selection Notes

Select this component when a single regulated output is sufficient for the design. The 2 MHz switching frequency allows for smaller external inductors compared to lower-frequency alternatives. Consider the 50 mA continuous load limit against the target application's power budget before finalizing the part choice.

Part Context

This part belongs to the ADP5304 series of ultra-low power DC-DC converters. It is designed specifically for space-constrained applications where minimizing board area and maximizing battery runtime are critical priorities. The device integrates most passive components internally to simplify the bill of materials.

Replacement Considerations

Check for ADP5301 variants if a different package type such as WLCSP is preferred. Verify functional equivalence with other single-output buck regulators from the manufacturer if supply chain adjustments are necessary.
