Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix #TRMPBF against official Analog Devices documentation to confirm tape-and-reel packaging and RoHS compliance status. Ensure the part number matches the exact electrical specifications required for your design, as minor variations exist within the LTC3620 family. Cross-reference datasheet revision dates to validate current manufacturing status and availability constraints.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.1V output is required from a 2.9V to 5.5V input source. The 15mA output current limit defines its suitability for low-power digital loads. Consider the 8-WFDFN package size for space-constrained PCB layouts. Verify thermal performance requirements given the small footprint and operating temperature range.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LTC3620 series of synchronous buck regulators. It shares architectural similarities with other members of the family but is distinguished by its fixed 1.1V output configuration. The series targets portable electronics and battery-operated equipment where efficiency and small form factor are critical design parameters.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Consult Analog Devices documentation for direct pin-compatible alternatives within the LTC3620 series. Verify that substitute parts maintain the same 1.1V fixed output and 15mA current capability. Check for any differences in switching frequency or package dimensions before implementation.
