Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify that the specific part number matches the required industrial temperature grade (-40°C to +125°C) and SOT223 package configuration. Confirm the ADJ suffix indicates the adjustable output version rather than fixed voltage variants. Ensure compliance with RoHS and lead-free requirements as specified in the manufacturer documentation before finalizing procurement orders.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when designing circuits that require adjustable voltage regulation under industrial environmental conditions. Consider the 1.35A current limit and dropout characteristics relative to the load requirements. Evaluate the need for external resistors to set the desired output voltage and ensure the selected output capacitor meets the low ESR compatibility criteria specified in the datasheet.
