ADP5033ACBZ-5-R7

Overview

The ADP5033ACBZ-5-R7 is a power management IC featuring two independent 800 mA buck regulators and two 300 mA low-dropout (LDO) regulators. It operates with an input voltage range of 2.3 V to 5.5 V and delivers fixed output voltages of 1.2 V, 1.5 V, 1.8 V, and 3.3 V. The device integrates a 3 MHz switching frequency for compact external component sizing. It supports a shutdown mode with a quiescent current of 380 uA. The unit is housed in a WLCSP-16 package and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Integrates dual high-current buck converters and dual LDOs in a single compact package
• Supports wide input voltage range suitable for single-cell lithium-ion battery applications
• Enables system power-down through integrated shutdown control functionality

Applications

• Portable consumer electronics requiring multi-rail power distribution
• Battery-powered devices utilizing single-cell lithium-ion sources
• Embedded systems needing combined switching and linear regulation

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm fixed output voltage configurations. Ensure the WLCSP-16 package footprint matches your PCB design constraints. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement specifications.

Selection Notes

Select this component when space-constrained designs require multiple regulated rails from a single source. The integrated buck regulators provide efficient step-down conversion while the LDOs offer clean power for sensitive analog sections. Evaluate thermal performance requirements based on the total load current across all four outputs.
