The SPX2937 offers 500m A output current with a dropout voltage of only 0.5V and over temperature dropout is up to 1V. The quiescent current is 10m A at differential output of 5V and output current of 500m A. A higher quiescent current can exist when the device is in dropout mode (VIN - VOUT≤ 3V ) The regulator will automatically shut down to protect both the internal circuits and the load. This device also features short circuit and thermal overload protection. The SPX2937 is offered in a 3-pin TO-220 package patible with other 5 volt and 3.3 volt regulators, TO-263 and SOT-223. This device offers a variety of output voltages 15V, 12V, 10V, 8V, 5V, 3.3V and 2.5V. SPX2937 is a direct replacement to LM2937.
