ADP5302ACPZ-3-R7

Overview

The ADP5302ACPZ-3-R7 is a high-efficiency, ultralow quiescent current step-down regulator 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 voltage from 800 mV to 5 V at up to 500 mA. The device features a typical static current of 240 nA and a switching frequency of 2 MHz. It is housed in a compact LFCSP-10 package and supports operation temperatures from -40°C to +125°C.

Feature Summary

• Ultralow quiescent current consumption for extended battery life
• High switching frequency enabling small external component size
• Integrated overcurrent protection and thermal shutdown

Applications

• Battery-powered portable electronics
• Industrial control systems
• Wireless sensor nodes

Procurement Notes

Verify the specific suffix '3' indicates the correct fixed or adjusted output configuration required for your design. Confirm package availability and lead times directly with authorized distributors as supply status may vary. Ensure compliance with RoHS directives if applicable to your region.

Selection Notes

Select this component when low standby power is critical alongside moderate load requirements. The 2 MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Verify that the desired output voltage falls within the 800 mV to 5 V range supported by the internal feedback network.

Part Context

This part belongs to the ADP5302 series of ultra-low power buck regulators. It is designed for applications requiring efficient power conversion from lithium-ion or alkaline batteries. The series emphasizes minimal footprint and maximum efficiency across varying load conditions.

Replacement Considerations

Check for pin-compatible alternatives within the same manufacturer's portfolio that offer similar quiescent current specifications. Ensure any substitute supports the required 500 mA output current and 2.15 V to 6.5 V input range.
