Overview
The LT3380HUJM#TRPBF is a multi-output power management IC from Analog Devices, integrating four buck switching regulators and three LDO linear regulators with I2C control. It operates within an input voltage range of 1.7 V to 5.5 V. The device provides output currents of up to 300 mA, 1.5 A, and 2.5 A across its channels. Output voltages are adjustable from 850 mV to 3.8 V. It functions reliably between -40°C and +150°C junction temperature, with a quiescent input current of 14 µA.
Feature Summary
- Integrates four buck switching regulators and three LDO linear regulators into a single compact package for comprehensive power distribution.
- Features digital configuration and monitoring capabilities via an I2C interface for flexible system control.
- Supports wide input voltage ranges suitable for various battery-powered and regulated supply applications.
Applications
- Portable medical equipment requiring multiple precise voltage rails
- Industrial instrumentation systems needing efficient power management
- Battery-operated devices utilizing low quiescent current operation
Procurement Notes
Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm that the HUJM grade meets your required operating temperature and performance specifications. Ensure I2C address configurations align with your system design constraints before finalizing procurement plans.
Selection Notes
Select this component when designing systems requiring seven distinct regulated outputs from a single IC footprint. Consider the trade-off between external component count and layout complexity. Verify that the maximum output current requirements of your loads do not exceed the specified limits for each respective regulator channel.
Part Context
This part belongs to the LT3380 series of multi-output power management solutions. It is designed to replace discrete regulator arrangements in space-constrained designs. The integration reduces board area while maintaining high efficiency through combined switching and linear regulation technologies.
Replacement Considerations
LT3380HUJM#PBF is a tube-packaged variant of the same functional device. Verify if the packaging format change affects your assembly process without altering electrical characteristics or pinout compatibility.
