Overview
The ADP5310AREZN-3.3R7 is a power management IC from Analog Devices, classified as a Buck Switching Regulator with an integrated LDO. It features two outputs: one fixed at 3.3V and one adjustable starting at 0.8V. The device supports a maximum switching frequency of 1200 kHz and accepts an input voltage range of 2.7 V to 15 V. Output currents are rated at 50 mA, 300 mA, and 800 mA across its channels. It is housed in a 16-TSSOP package with an exposed pad and operates within a temperature range of -40°C to +105°C.
Feature Summary
- Integrates a high-efficiency buck switching regulator with an embedded low-dropout linear regulator for combined power delivery.
Applications
- Portable electronic devices requiring efficient multi-rail power supply
- Battery-powered systems utilizing lithium-ion or lithium-polymer cells
- Embedded applications needing compact power management solutions
Procurement Notes
Verify the specific suffix R7 indicates reel packaging when ordering. Confirm that the 3.3 variant matches the required fixed output voltage for your design. Ensure the 16-TSSOP footprint aligns with your PCB layout constraints. Check current availability status as supply may be limited or subject to factory special orders. Validate RoHS compliance requirements against your manufacturing standards before finalizing procurement.
Selection Notes
Select this component when a single-chip solution for dual-output power regulation is needed. It is suitable for designs prioritizing space efficiency due to the TSSOP package. Consider the 1200 kHz switching frequency for smaller external passive components. Ensure the input voltage range up to 15 V covers your system's maximum supply. Verify thermal performance requirements given the exposed pad package type.
Part Context
This part belongs to the ADP5310 series of ultra-low power buck PMUs. It is designed for portable applications where battery life and board space are critical. The series integrates switching and linear regulation to provide stable voltages for microprocessors and memory. It represents a consolidated approach to power management compared to discrete regulator solutions.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult official Analog Devices resources for cross-reference data if alternative sourcing is required.
