Texas Instruments MLTLDO2EVM-037 Regulator Evaluation Module (EVM) helps design engineers evaluate the operation and performance of linear regulators for possible use in their circuit application. The Texas Instruments MLTLDO2EVM-037 offers four linear regulator designs, each one electrically isolated from the other through tab routing in the PCB fabrication step. The boards can be quickly separated through the breakaway tabs if desired. Combined, the boards can mount many linear regulators that come in the DDA, DCY, 3-pin KVU, and 5-pin KVU packages.
The boards that carry the DDA, DCY, and 3-pin KVU packages have been designed to withstand up to 100VDC of voltage across its input and output terminals. The board that carries the 5-pin KVU package has been designed to withstand up to 50VDC of voltage across its input and output terminals. All four boards have been designed to withstand 5ADC of current draw. This design allows the evaluation module to be used for numerous linear regulator designs in TI’s portfolio, as well as future designs that may operate into high voltage or high current.
Each board is designed to populate multiple input and output capacitors, allowing the user to customize the evaluation module for their specific needs. User-selectable grounding is available on each board, allowing the user to evaluate the linear regulator in a floating application. Thermal vias have been placed near each linear regulator to aid in the thermal spreading of the heat generated by the device. The evaluation module comes with four bumpons to lift the evaluation module off of the test surface, and mounting holes are provided for standoffs or mounting to an external chassis.
