ADP5300ACPZ-4-R7

Overview

The ADP5300ACPZ-4-R7 is a fixed-output ultra-low power (ULP) buck switching regulator manufactured by Analog Devices Inc. It provides a fixed 3.6 V output with a maximum continuous current of 500 mA. The device operates from an input voltage range of 2.15 V to 6.5 V and features a quiescent current of 425 uA. It utilizes a 2 MHz switching frequency and is housed in a compact LFCSP-10 package. The component supports shutdown functionality and operates within a temperature range of -40°C to +125°C.

Feature Summary

• Ultra-low power architecture designed for battery-operated applications
• Integrated synchronous buck topology for high efficiency
• Fixed 3.6 V output configuration without overvoltage protection

Applications

• Portable consumer electronics requiring efficient step-down regulation
• Battery-powered sensor nodes and IoT devices
• Embedded systems utilizing low-voltage logic supplies

Procurement Notes

Verify the specific suffix '-4' confirms the fixed 3.6 V output variant, as other suffixes indicate adjustable or different fixed voltages. Confirm availability status, as supply may be limited or subject to factory special orders. Ensure compatibility with LFCSP-10 footprint requirements during procurement planning.

Selection Notes

Select this part when a fixed 3.6 V rail is required at up to 500 mA with minimal external components. Consider the 2 MHz switching frequency for smaller passive size compared to lower frequency alternatives. Evaluate thermal performance under load given the small LFCSP-10 package dimensions.

Part Context

This component belongs to the ADP5300 series of ultra-low power buck regulators. It is distinct from adjustable variants like the ADP5300ACPZ-1-R7, which offers programmable output voltages. The ADP5300-EVALZ development board is available for testing this family's performance characteristics.
