The fixed output eliminates the need for external resistor dividers. ## Protection and temperature grade Built-in protection against over-temperature, reverse polarity, and short circuit makes this regulator suitable for environments where supply faults or load faults are expected — think industrial control panels, motor drive auxiliary rails, or automotive body electronics. ## Package and dropout Housed in a SOT-223-4 (TO-261AA) surface-mount package, the LM2937IMPX-10 suits compact PCB layouts. The maximum dropout voltage is 1 V at 50 mA load, which means the input must stay above 11 V to maintain regulation at light loads; at full 400 mA the dropout will be higher, so budget at least 1.5 V headroom for the full current range.","metaTitle":"LM2937IMPX-10 Fixed 10V 400mA LDO Regulator, SOT-223-4","metaDescription":"LM2937IMPX-10 fixed 10V output LDO, 400mA, SOT-223-4.
