Inspire the Linear Power  
1.25A High Current Low Dropout  
LM3940  
Voltage Regulator for Convert 5V & 3.3V  
Description  
The Bay Linear LM3940 is a 1.25A high accuracy, low dropout  
voltage regulator with only 40mV at light loads and  
350mV(Typ.)@ 1.0A) and low quiescent current of 240µA typical.  
Features  
High output accuracy of 1%  
Fix Output 5.0v & 3.3V  
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-252, TO-220, SOT-223, &  
New Slim LPDD  
The LM3940 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.  
Similar to industry Standard LM3940  
The LM3940 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%.  
Applications  
Powering VGA & Sound Card  
LCD Monitor  
The LM3940 are offered in a 3-pin SOT-223, TO-220 & TO-263  
package compatible with other 3 terminal regulators. The LM3940  
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) total  
tickness.
