LMH/ Texas Instruments Linear Voltage Regulators LMH/ Voltage Regulator datasheet, inventory, & pricing. The LM/LMC is a voltage regulator designed prima- rily for series regulator applications. By itself, it will supply output currents up to mA; but external. The LM is a monolithic integrated programmable voltage regulator, assembled in. lead dual in-line plastic package. The circuit provides internal current.

The design followed relatiovely logically from what was available at that time. If you use a resistor to turn the on and the to turn it off, the will need to be sinkig most of datashet current when idle and so must be used near its current rating often. Note that only the DIP package has the Vz pin–the output from the zener diode which is used for negative regulators. Also able to use as either linear or switching type regulator. Pin configuration Pin No.
Q1 is driven on by the ”s output transistor and in turn it drives Q3. Agreed – the inverting pin is fed by a very “interesting” arrangement – in fact that’s the exact part that confuses me besides the Vz being pulled to ground. I have also spent about half a day playing around with the various configurations on the datasheet to try and get a feel for how it works.
Thank you very much for your reply, this explains a lot in only a few lines. But again, all with certain limitations. For 2A current limit R10 is about 0. Views Read View source View history. We are heading down the sad “vote to close” road again on a very interesting question that COULD teach more design to those who wish to learn than any amount of “plug in an LM” questions ever will. This will be compared to a sample of the Vout voltage.
I think the is okay because I did swap it with another with no difference. Put the sense resistor divider on the Vout side of the resistors.
LM IC Pinout, Specifications, Equivalent & Datasheet
SO Texas Instruments part: All the zener does in the diagram there is provide a stable voltage between pins 9 and 10, correct? The problem was traced to the The metal can and the flat-pack do not have enough pins and so they skip this one.
This circuit is the first time I’ve seen datashret used in any schematic.
Indeed I’ve been looking through several dataeheet, the latest ones from TI being the most robust got them from Jameco. Most transistors “explode” in experimental situations because they are connected wrong.
If you change k in steps of 2. Is that due to pin 9 being grounded? LM was the bees knees voltage regulator controller and maybe also the only one readily datasheeh ‘way back when’.
This has led me into investigating the schematic, but try as I might, I can’t make heads nor tails of what’s going on.
The Voltage Regulator Description: With 35V in you can get about 1. Datashewt tested it with a 5-ohm power resistor. This is very much a design question and of great value to any who want to move beyond the “plug in a black box l723h type of “design”. I’ve added DIP pin numbers as those match what you show. Sorry I can’t remember which pins.

The LM’s primary intended function is to “regulate” a DC voltage. There are two aspects to this. As for the zener diode question I’m sorry that wasn’t very clear. When you study the data sheets, you will see that you can use the LM “on its own”, though with a few necessary external resistors and capacitors. I’ve attached the circuit diagram.
I’m trying to troubleshoot a delinquent power supply I have. See at end for specific details of your circuit’s operation. On the functional block diagram of thepin 9 is the output directly below a zener diode. This page has been accessed 30, times.
It can able to provide a higher range of output voltage and current up to 10A by simply adding a series pass transistor with it, with having a wider range of operating temperature so the IC able to withstand for long. Sign up using Facebook. The common zero point of 6.
