

*Parts ending with PBF are RoHS and WEEE compliant.



**Tape and reel specifications. Some packages are available in 500-unit reels through designated sales channels

with #TRMPBF suffix.



***Pad or ball finish code is per IPC/JEDEC J-STD-609.



****The temperature grade is identified by a label on the shipping container.



*****The LT83203/LT83205 package has the same dimensions as a standard 3mm × 2mm LFCSP package.



******The LT83203/LT83205 is specified over the –40°C to 150°C operating junction temperature range. High

junction temperatures degrade operating lifetimes. The junction temperature (TJ, in °C) is calculated from the

ambient temperature (TA in °C) and power dissipation (PD, in Watts) according to the formula: TJ = TA + (PD × θJA),

where θJA (in °C/W) is the package thermal impedance.



For parts specified with wider operating temperature ranges, contact the factory.



For recommended LGA and BGA PCB assembly and manufacturing procedures, refer to the Recommended LGA

and BGA PCB Assembly and Manufacturing Procedures.



For LGA and BGA package and tray drawings, refer to the LGA and BGA Package and Tray Drawings.
