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 .

CMOS Technology file 1. With no load the quiescent current is only 2mA. Post as a guest Name. Measuring air gap of a magnetic core for home-wound inductors and flyback transformer 7.

But when I put my 12v on input, I only measure 3V as output instead of Indeed I did not paid attention to this ; I tested with a 10uF cap but I have like a big voltage drop from 12 to 3V when I measure my input and I don’t know why. Input and output are reversed, which I suspect simply shorts the output of LM ModelSim – How to force a struct type written in SystemVerilog?

The specification you are reading is quiescent current when the regulator is delivering Imax mA or mA output. Choosing IC with EN signal 2. In fact, if you use DPDT then why do you need negative converter at all? You are not loading it that much, I assume. From reading the datasheetyou seem to be missing a bigger capacitor on the LM’s output. Sign up using Facebook.
