Product details

Fixed 10V LDO with 500 mA output and industrial temp range

The LM2937ES-10 is a fixed-output positive LDO regulator delivering 10V at up to 500 mA continuous current. The 1V maximum dropout at 50 mA load means it holds regulation even when the input rail sags close to 11V — useful in battery-backed or lightly regulated 12V systems.

Protection features and quiescent current

Built-in protection against over-temperature, reverse polarity, and output short circuit. The 2 mA quiescent current is modest for a 500 mA LDO — the supply pin won't waste rail capacity when the load is light. Maximum supply current is 20 mA, so the part draws negligible overhead even at no load.

The part is RoHS non-compliant, which may complicate use in new designs bound for EU markets. We can quote to order against your quantity — confirm the package (Tube, TO-263-4 D²Pak) and the fixed 10V output match your board before committing.
