ADP5033ACBZ-2-R7

Overview

The ADP5033ACBZ-2-R7 is a power management IC featuring two high-performance buck regulators and two low dropout (LDO) regulators. It operates with an input voltage range of 2.3 V to 5.5 V. The buck regulators provide up to 800 mA output current, while the LDOs deliver 300 mA each. The device supports a switching frequency of 3 MHz and offers four outputs. It functions within a temperature range of -40°C to +125°C and is housed in a WLCSP-16 package.

Feature Summary

• Integrates dual synchronous buck converters and dual LDOs for compact board space utilization
• Supports forced PWM and auto PWM/PSM modes for optimized light-load efficiency
• Provides high PSRR and low output noise from the LDO sections

Applications

• Powering processors, ASICs, FPGAs, and RF chipsets
• Portable instrumentation and medical devices
• Space-constrained electronic designs

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm fixed output voltages. Confirm availability status as distribution channels may list limited stock or end-of-life conditions. Ensure the WLCSP-16 footprint matches your PCB layout requirements before finalizing procurement orders.

Selection Notes

Select this component when multiple regulated rails are required in a minimal footprint. The integrated buck and LDO topology reduces external component count. Verify that the fixed output voltages meet system requirements, as adjustable variants exist within the same family. Consider thermal performance under maximum load conditions.

Part Context

This part belongs to the ADP5033 series, which combines switching regulators and linear regulators in a single package. The ACBZ-2 suffix typically denotes specific factory-programmed output voltages. It is designed to replace discrete regulator solutions in mobile and portable applications where size and efficiency are critical constraints.

Replacement Considerations

Check ADP5033ACBZ-1-R7 and ADP5033ACBZ-3-R7 for alternative fixed voltage configurations within the same package and electrical specifications.
