Dropout Voltage Typically 0.5V @IO = 1A  
Output Current in Excess of 1A  
features the ability to source 1A of output current with  
a dropout voltage of typically 0.5V and a maximum of  
1V over the entire temperature range. Furthermore, a  
quiescent current reduction circuit has been included  
which reduces the ground current when the  
differential between the input voltage and the output  
voltage exceeds approximately 3V. The quiescent  
current with 1A of output current and an input-output  
differential of 5V is therefore only 30 mA. Higher  
quiescent currents only exist when the regulator is in  
the dropout mode (VIN − VOUT ≤ 3V).  
Output Voltage Trimmed Before Assembly  
Reverse Battery Protection  
Internal Short Circuit Current Limit  
Mirror Image Insertion Protection  
P+ Product Enhancement Tested  
Designed also for vehicular applications, the LM2940-  
N/LM2940C and all regulated circuitry are protected  
from reverse battery installations or 2-battery jumps.  
During line transients, such as load dump when the  
input voltage can momentarily exceed the specified  
maximum operating voltage, the regulator will  
automatically shut down to protect both the internal  
circuits and the load. The LM2940/LM2940C cannot  
be harmed by temporary mirror-image insertion.  
Familiar regulator features such as short circuit and  
thermal overload protection are also provided.  
Typical Application  
*Required if regulator is located far from power supply filter.  
**COUT must be at least 22 μF to maintain stability. May be increased without bound to maintain regulation during  
transients. Locate as close as possible to the regulator. This capacitor must be rated over the same operating  
temperature range as the regulator and the ESR is critical; see curve.
