1 / 4 page Rev. 10/30/00 SPX2937 500mA Low Dropout Voltage Regulators (PRELIMINARY INFORMATION) FEATURES APPLICATIONS • Output Current 500mA at 15V, 12V, 10V, 8V, 5V, 3.3V and 2.5V • Battery Powered Systems • Internal Short Circuit Current Limit • Cordless Telephones • Dropout Voltage 0.5V at 500mA Output • Automotive Electronics • Extremely Tight Load and Line Regulation • Portable/ Palm Top / Notebook Computers • Very Low Temperature Coefficient • Portable Consumer Equipment • Mirror Image Insertion Protection • Portable Instrumentation • Direct Replacement For LM2937 Socket • SMPS Post-Regulator • Voltage Reference 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 (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 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.
