Specifications and operating details
The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.
- Separate versions are available for 3.3V and 5V power supplies.
- The dual voltage CAN transceiver and the adjustable regulator allow 3.3V or 5V isolated power with either the 3.3V or 5V version.
- A logic supply pin allows easy interfacing with different logic levels from 1.62V to 5.5V, independent of the main supply.

- 10) LTM2889-5 l 3.0 3.3 3.5 V VCC2 Short Circuit Current VCC2 = 0V, TXD = VL 200 mA The l denotes specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C.
- Unless otherwise noted, the following conditions apply: PVCC = VCC = 3.3V for the LTM2889-3, PVCC = VCC = 5V for the LTM2889-5, VL = 3.3V, GND = GND2 = S = RE = RS = 0V, ON = VL.
- Figure 10 applies for VCC2 = 3.3V; otherwise ADJ is floating.

Engineering review checklist
- Confirm the exact ordering code, package, pinout or terminal arrangement and document revision.
- Compare recommended operating conditions with absolute maximum ratings and retain adequate design margin.
- Validate electrical, thermal, mechanical and environmental behavior in the final application.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
