Procurement Notes

Verify the specific suffix #TRMPBF against official Analog Devices documentation to confirm tape and reel packaging specifications. Ensure compatibility with surface-mount assembly processes for the TSOT-23-6 package. Cross-reference the part number with the manufacturer's latest datasheet to validate RoHS compliance status and environmental declarations prior to integration into production designs.

Selection Notes

Select this component when designing circuits requiring a compact solution for stepping down higher voltages to lower levels with minimal quiescent current consumption. The adjustable output feature allows flexibility in setting target voltages via external resistors. Consider the thermal performance within the TSOT-23-6 package constraints and ensure the input voltage does not exceed the 34 V maximum rating during transient conditions.

Part Context

This part belongs to the LT1934 series of micropower step-down switching regulators. It is designed for applications where space is limited and low standby current is critical. The ES6 designation indicates the TSOT-23-6 package variant.
