... Connection Diagrams TO-252, Top View LP38691DT-X.X 6-Lead LLP, Top View LP38691SD-X.X Pin Descriptions Pin V This is the input supply voltage to the regulator. For LLP devices, both V IN for full current operation (250mA maximum per pin). GND Circuit ground for the regulator. For the TO-252 and SOT-223 packages this is thermally connected to the die and functions as a heat sink when the soldered down to a large copper plane ...
