DESCRIPTION  
The UTC LM2937 is a positive voltage regulator capable of  
supplying up to 500mA of load current. The use of a PNP power  
transistor provides a low dropout voltage characteristic. With a  
load current of 500mA 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 operating  
temperature range). Special circuitry has been incorporated to  
minimize the quiescent current to typically only 10mA with a full  
500mA load current when the input to output voltage differential is  
greater than 3V.

TO-263-3  
The UTC LM2937 requires an output bypass capacitor for  
stability. As with most low dropout regulators, the ESR of this  
capacitor remains a critical design parameter, but the LM2937  
includes special compensation circuitry that relaxes ESR  
requirements. The UTC LM2937 is stable for all ESR below  
3Ω.This allows the use of low ESR chip capacitors.

TO-263-5  
Ideally suited for automotive applications, the UTC LM2937 will  
protect itself and any load circuitry from reverse battery  
connections, 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.

* Typical dropout voltage of 0.5V at full rated load current  
* Wide output capacitor ESR range, up to 3ꢀ  
* Reverse battery protection  
* Internal short circuit and thermal overload protection  
* 60V input transient protection  
* Mirror image insertion protection  
* Built-in ON/OFF control function
