LM2940/LM2940C  
1A Low Dropout Regulator  
General Description  
age, the regulator will automatically shut down to protect both  
the internal circuits and the load. The LM2940/LM2940C can-  
not be harmed by temporary mirror-image insertion. Familiar  
regulator features such as short circuit and thermal overload  
protection are also provided.  
The LM2940/LM2940C positive voltage regulator 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 temper-  
ature range. Furthermore, a quiescent current reduction cir-  
cuit 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).  
Designed also for vehicular applications, the LM2940/  
LM2940C and all regulated circuitry are protected from re-  
verse battery installations or 2-battery jumps. During line  
transients, such as load dump when the input voltage can  
momentarily exceed the specified maximum operating volt-

Dropout voltage typically 0.5V @IO = 1A

*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.
