LM2937  
500 mA Low Dropout Regulator  
nections, two-battery jumps and up to +60V/−50V load dump  
transients. Familiar regulator features such as short circuit  
and thermal shutdown protection are also built in.  
General Description  
The LM2937 is a positive voltage regulator capable of sup-  
plying up to 500 mA of load current. The use of a PNP power  
transistor provides a low dropout voltage characteristic. With  
a load current of 500 mA the minimum input to output voltage  
differential required for the output to remain in regulation is  
typically 0.5V (1V guaranteed maximum over the full operat-  
ing temperature range). Special circuitry has been incorpo-  
rated to minimize the quiescent current to typically only  
10 mA with a full 500 mA load current when the input to out-  
put voltage differential is greater than 3V.  
Features  
n Fully specified for operation over −40˚C to +125˚C  
n Output current in excess of 500 mA  
n Output trimmed for 5% tolerance under all operating  
conditions  
n Typical dropout voltage of 0.5V at full rated load current  
n Wide output capacitor ESR range, up to 3  
n Internal short circuit and thermal overload protection  
n Reverse battery protection  
n 60V input transient protection  
n Mirror image insertion protection  
The LM2937 requires an output bypass capacitor for stabil-  
ity. As with most low dropout regulators, the ESR of this ca-  
pacitor remains a critical design parameter, but the LM2937  
includes special compensation circuitry that relaxes ESR re-  
quirements. The LM2937 is stable for all ESR below 3. This  
allows the use of low ESR chip capacitors.  
Ideally suited for automotive applications, the LM2937 will  
protect itself and any load circuitry from reverse battery con-
