LM2941/LM2941C  
1A Low Dropout Adjustable Regulator  
automatically shut down to protect both the internal circuits  
and the load. Familiar regulator features such as short circuit  
and thermal overload protection are also provided.  
General Description  
The LM2941 positive voltage regulator features the ability to  
source 1A of output current with a typical dropout voltage of  
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 pin current when  
the differential between the input voltage and the output volt-  
age 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 LM2941 and all  
regulated circuitry are protected from reverse battery instal-  
lations or two-battery jumps. During line transients, such as  
load dump when the input voltage can momentarily exceed  
the specified maximum operating voltage, the regulator will
