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 .

Besides, the pads on PCB are obviously dahasheet large electrolytic. Also, it is bad idea to use internal connection between tab and ground pins of LM Dec 248: The time now is The load on the 3.

Maple 4, 2 3 The pads are mixed up. The specification you are reading is quiescent current when the regulator is delivering Imax mA or mA output.

AF modulator in Transmitter what is the A? Pin 8 in voltage input and pin 5 voltage output; isn’t it? How reliable is it? You are not loading it that much, I assume. I know it’s strange the output will be the curseur of potentiometer.

From reading the datasheetyou seem to be missing a bigger capacitor on the LM’s output. Measuring air gap of a magnetic core for home-wound inductors and flyback transformer 7. Apparently, fatasheet didn’t pay attention to many things. Either leave tab floating or better connect them together, exactly as datasheet recommends.
