LT117AK is listed in the Voltage Regulators - Linear, Low Drop Out (LDO) Regulators range at ChipApex. The manufacturer field lists Analog Devices Inc.. Its product description is IC REG LINEAR POS ADJ TO3. Review the specifications below when checking this part for your BOM.
The LT117AK is a high-voltage positive adjustable linear regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3V to 40V and provides an adjustable output voltage from 1.25V to 37V. The device supports a maximum output current of 1.5A and features internal current limiting and thermal overload protection. Packaged in the TO-257 (TO-39) metal can, it is designed for applications requiring robust performance under high differential input-output voltages.
Verify the specific suffix 'AK' against official Analog Devices documentation to confirm package type and temperature grade. Ensure compatibility with TO-257 mounting requirements. Cross-reference part numbers with Linear Technology archives if sourcing legacy inventory. Confirm RoHS compliance status through manufacturer datasheets prior to procurement.
Select this component when designing circuits requiring adjustable regulation up to 40V input. Consider the TO-257 package for high-power dissipation needs. Evaluate thermal management strategies due to potential heat generation at high differential voltages. Compare against modern LDO alternatives if size constraints exist.
