ADP5024ACPZ-1-R7

Voltage Regulators - Linear + Switching Overview

The ADP5024ACPZ-1-R7 is a fixed-output buck switching regulator from Analog Devices, housed in a 24-lead LFCSP package. It provides three independent outputs with voltages of 1.2 V, 2.8 V, and 3.3 V. The device supports output currents up to 1.2 A and 300 mA depending on the channel. It operates within an input voltage range of 2.3 V to 5.5 V and features a low quiescent current of 10 uA. The integrated switch operates at a frequency of 3 MHz, enabling compact designs. It functions reliably across a temperature range of -40°C to +125°C.

Voltage Regulators - Linear + Switching Feature Summary

• Integrates three synchronous buck converters for multi-rail power distribution
• Features ultra-low quiescent current for extended battery life in standby modes
• Utilizes high-frequency operation to minimize external component size
• Includes undervoltage lockout (UVLO) for reliable startup sequencing

Voltage Regulators - Linear + Switching Applications

• Portable consumer electronics requiring multiple fixed voltage rails
• Battery-powered devices needing efficient power management
• Embedded systems with strict space constraints
• Industrial control modules operating in wide temperature ranges

Voltage Regulators - Linear + Switching Procurement Notes

Verify the specific suffix '-1' confirms the fixed output configuration of 1.2V, 2.8V, and 3.3V. Confirm the 'R7' tape and reel packaging quantity matches design requirements. Check for moisture sensitivity level (MSL) handling instructions due to LFCSP packaging. Ensure compatibility with existing PCB footprint for the 24-lead LFCSP-EP package before finalizing procurement.

Voltage Regulators - Linear + Switching Selection Notes

Select this part when fixed voltage rails are sufficient, eliminating the need for external resistors. Compare against adjustable variants if flexible voltage settings are required later. Consider the 3 MHz switching frequency for trade-offs between efficiency and electromagnetic interference. Verify that the total output current requirements do not exceed the thermal limits of the LFCSP package under expected ambient conditions.

Voltage Regulators - Linear + Switching Part Context

This component belongs to the ADP5024 family of micro power management units designed for space-constrained applications. It shares the same physical footprint and evaluation board infrastructure with other ADP5024 variants, such as adjustable output versions. This simplifies design reuse and manufacturing processes across different product lines within the same ecosystem.

Voltage Regulators - Linear + Switching Replacement Considerations

Direct substitutes include other ADP5024 variants with different output configurations or the ADP5037 for additional channels. Verify pin-to-pin compatibility and electrical parameter alignment before substitution.
