SPX2937
500mA Low Dropout Voltage Regulators
(PRELIMINARY INFORMATION)
FEATURES
Output Current 500mA at 15V, 12V, 10V, 8V, 5V, 3.3V and 2.5V
Internal Short Circuit Current Limit
Dropout Voltage 0.5V at 500mA Output

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.
