Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and tube packaging when sourcing. Confirm the DDPAK-5 package variant matches your PCB footprint requirements. Check official Analog Devices documentation for the latest RoHS and REACH status updates. Ensure the operating temperature range aligns with your system's environmental constraints before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for applications requiring a robust bipolar switching regulator with integrated power switching capabilities. The fixed 100 kHz frequency allows for compact external passive component selection. Consider the 1.6 A output limit and 45 V maximum input voltage when designing the power stage. Verify thermal performance requirements given the surface-mount package type.

Voltage Regulators - DC DC Switching Regulators Part Context

The LT1076 belongs to a family of monolithic bipolar switching regulators designed for high-efficiency DC/DC conversion. Unlike modern CMOS-based controllers, this device integrates the main power switch internally, reducing external component count. It serves as a foundational solution for industrial and commercial power supplies where reliability and simplicity are prioritized over ultra-low quiescent current.
