Package Information PACKAGE TYPE: 10-PIN THIN LGA Package Code L1022+2 Outline Number 21-100265 Land Pattern Number 90-100101 THERMAL RESISTANCE, SINGLE-LAYER BOARD: Junction to Ambient ( ) 241.30C/W JA Junction to Case ( ) 53.90C/W JC For the latest package outline information and land patterns (footprints), go to www.maximintegrated.com/packages. Note that a +, , or - in the package code indicates RoHS status only. Package drawings may show a different suffix character, but the drawing pertains to the package regardless of RoHS status. Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer board.
