The LM2940/41 is designed for low voltage a application that requires lower dropout voltage and faster transient response. This device is an excellent choice for use in powering low voltage applications where require a lower dropout, faster transient response to regulate from +2.5V to 3.8V supplies and as a post regulator for switching supplies applications. The LM2940/41 offers full protection against over-current faults, reversed input polarity, reversed load insertion, and positive and negative transient voltage. On-Chip trimming adjusts the reference voltage to 1%. The LM2940-xx devices are in 3 pin fixed voltage regulators. The LM2941 include an Enable pin in the 5 pin packages . The LM2940/41 are offered in a 3 & 5-pin SOT-223, TO-220 & TO-263 package compatible with other 3 terminal regulators. The LM2940/41 is also offer in a new LPDD (Low Profile TO-263) package from 4.47 mm (DD) tickness down to only 1.27 mm (LPDD) t t l ti k Features • High output accuracy of 1% • Output Adjustable from 1.24V to 26V • Output Current of 1.25A • Low Dropout Voltage • Low quiescent current • Extremely Tight Load & Line Regulation • Reverse-battery and “Load Dump” Protection • Zero Current Shutdown Mode (5-pin version) • Offer in TO-263, TO-220, SOT-223, & New Slim LPDD • Similar to industry Standard MIC2940LM2941 Applications • Powering VGA & Sound Card • LCD Monitor • Battery Powered Equipments/Laptop & Notebook • SMPS Post Regulator / DC to DC Modules • High Efficiency Linear Power Supply • Adjustable Power Supply • Bar Code Scanners Bay Linear Inspire the Linear Power TO-263-3 Package V OUT GND V IN BAY B2940 Front View 12 3 Front View TO-220-3 Package BAY B2940 V IN V OUT GND TO-263-5 Package Top View 45 BAY B2941 3 2 1 GND OUPUT 1) 3) 4) 5) 2) ON/OFF ADJUST INPUT TO-220-5 Package Top View BAY B2941 12 3 4 5 TO-263-3 Package V OUT GND V IN BAY B2940 Front View 12 3 Front View TO-220-3 Package BAY B2940 V IN V OUT GND TO-263-3 Package V OUT GND V IN BAY B2940 Front View 12 3 Front View TO-220-3 Package BAY B2940 V IN V OUT GND Front View TO-220-3 Package BAY B2940 V IN V OUT GND TO-263-5 Package Top View 45 BAY B2941 3 2 1 GND OUPUT 1) 3) 4) 5) 2) ON/OFF ADJUST INPUT TO-220-5 Package Top View BAY B2941 12 3 4 5 TO-263-5 Package Top View 45 BAY B2941 3 2 1 GND OUPUT 1) 3) 4) 5) 2) ON/OFF ADJUST INPUT GND OUPUT 1) 3) 4) 5) 2) ON/OFF ADJUST INPUT TO-220-5 Package Top View BAY B2941 12 3 4 5 TO-220-5 Package Top View BAY B2941 12 3 4 5 |
