PRODUCT DESCRIPTION
The SPX2937 is a low power positive voltage regulator. The SPX2937 offers 500mA output current with a dropout voltage of only
0.5V and over temperature dropout is up to 1V. The quiescent current is 10mA at differential output of 5V and output current of
500mA. A higher quiescent current can exist when the device is in dropout mode (V_IN - V_OUT≤ 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 compatible 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.
