OM2940STM  
0.5 VOLT LOW DROPOUT POSITIVE FIXED VOLTAGE  
REGULATOR APPROVED TO DESC DRAWING  
Three Terminal, Fixed Voltage, 1 Amp  
Low Dropout Voltage Regulator In  
Hermetic JEDEC TO-257AA Package  
FEATURES  
• Similar To Industry Standard LM2940  
• Approved To DESC Standardized Military Drawing  
• Dropout Voltage Typically 0.5 V @ IO = 1 A  
• Output Current in Excess of 1 A  
• Reverse Battery Protection  
• Internal Short Circuit Protection  
• Isolated Hermetic Package  
DESCRIPTION  
These three terminal fixed voltage regulators are designed to provide 1.0A with high  
efficiency. It has the ability to source 1A of output current with a typical dropout  
voltage of .5V and a maximum of 1V over the entire temperature range. It is supplied  
in the hermetic TO-257 package and is ideally suited for Military applications where  
small size and high reliability is required.
