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 .

The pin numbers are correct. Either leave tab floating or better lmm2937 them together, exactly as datasheet recommends. I don’t think there is such thing as 22 nF polarized capacitor. The time now is I know it’s strange the output will be the curseur of potentiometer.
