ADP5301ACBZ-2-R7

Overview

The ADP5301ACBZ-2-R7 is a high-efficiency, ultralow power step-down DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 2.15 V to 6.5 V and provides a single adjustable output ranging from 800 mV to 5 V. The device delivers up to 500 mA of output current while maintaining a typical quiescent current of 180 nA. It integrates a 2 MHz switching frequency and supports synchronous rectification for improved efficiency. The component is housed in a 9-WLCSP package and functions within a junction temperature range of -40°C to +125°C.

Feature Summary

• Integrates ultralow quiescent current architecture for extended battery life in portable applications
• Features synchronous buck topology with fixed 2 MHz switching frequency to minimize external component size
• Includes programmable soft-start and shutdown control for system power management

Applications

• Wearable electronic devices requiring minimal standby power consumption
• Portable consumer electronics powered by single-cell lithium-ion or lithium-polymer batteries
• IoT sensor nodes and wireless communication modules

Procurement Notes

Verify the specific suffix code against the manufacturer datasheet to confirm pinout and functional configuration. Ensure the ordering part number matches the required output voltage range and package type. Confirm RoHS compliance status through official documentation before procurement. Cross-reference the manufacturer part number with authorized distributor catalogs to avoid counterfeit components.

Selection Notes

Select this regulator when input voltages vary between 2.15 V and 6.5 V and output currents up to 500 mA are required. Choose this model over linear regulators when higher efficiency is needed under light load conditions. Consider the 9-WLCSP package constraints for PCB layout density. Verify that the required output voltage falls within the 800 mV to 5 V adjustable range defined by the feedback network.

Part Context

This component belongs to the ADP5301 series of ultralow power step-down regulators designed for battery-operated systems. It shares the same core topology and package style as variants like the ADP5301ACBZ-1-R7, differing primarily in internal programming configurations or output ranges. The series targets applications demanding high efficiency at low currents.
