SPX2937

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 Extremely Tight Load and Line Regulation Very Low Temperature Coefficient Mirror Image Insertion Protection Direct Replacement For LM2937 Socket APPLICATIONS Battery Powered Systems Cordless Telephones Automotive Electronics Portable/ Palm Top / Notebook Computers Portable Consumer Equipment Portable Instrumentation 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.
