LM2937 DATASHEET PDF

The LM is a positive voltage regulator capable of sup- plying up to mA of load current. The use of a PNP power transistor provides a low dropout. The LM is a positive voltage regulator capable of sup- plying up to mA of load current The use of a PNP power transistor provides a low dropout voltage . The LM and LM are positive voltage regu- lators capable of supplying up to mA of load current. Both regulators are ideal for converting a .
