LM723H DATASHEET PDF

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.

As for the zener diode question I’m sorry that wasn’t very clear. This page was last modified on 19 Aprilat I think the is okay because I did swap it with another with no difference. The Model T of the power transistor world.

See at end for specific details of your circuit’s operation. Don’t worry, this question won’t stay closed. Xatasheet checked theand it has ohms from emitter to base i. Go above this and kaput!

But again, all with certain limitations. I have seen another LM in almost the exact same setup elsewhere, but the site was in Russian. This circuit is the first time I’ve seen it used in any schematic. I don’t see a “zener diode” in the schematic.

SO Texas Instruments part: Sign up using Facebook. I am just reading through all the responses now. I’ve added DIP pin numbers as those match what you show. 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 output transistor 10,11 drives the external pass element. Get each one as they usually contain the same information presented in different ways.

National Semiconductor

A was used to regulate the HV output 15KV. The common zero point of 6. It is a pin IC that needs some outboard components to tell it what to do.

TL — Programmable Reference Voltage.

If it is a 1 Watt it might last a long time. The Voltage Regulator Description: If you change k in steps of 2. I haven’t finished the functional description above but the added material should give you a very good insight into operation. For finding the value of output voltage for this circuit you can use the formula below:. Thanks again for your time. For getting an output voltage range from 2v to 7v you can use the circuit below, which is a Basic Voltage Regulator circuit using LM voltage regulator IC.

Voltage Regulator

Thank you for your response! Then study the example application circuits given in it. Closing would be very sad. However, it will only regulate a maximum output current of about milliamps. With the voltage turned right down of course. 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.

About 15 years ago I worked for a HV power supply company.

LM IC Pinout, Specifications, Equivalent & Datasheet

All the zener does in the diagram there is provide a stable voltage between pins 9 and 10, correct? Secondly, apologies to those who feel this question wasn’t researched enough nor novel. The problem was traced to the It is available as a pin DIP from everyone. Q1 is ,m723h on by the ”s output transistor and in turn it drives Q3. But, if you’d done dtaasheet before working out how it worked you’d have learned far less: Votes to close are disappointing.

None the less, I’m going to look up the datasheet and give her a test. Indeed I’ve been looking through several datasheets, the latest ones from TI being the most robust got them from Jameco.

Unless I am missing it, I don’t see a zener diode on that schematic anywhere. Q2 is for short-circuit protection- it detects the voltage across R Home Questions Tags Users Unanswered. The error amplifier 4 5 inputs is used to compare a reference voltage with the voltage to be controlled.

BUT the sinks current to ground as it turns on although you can invert the error amp sense and use a pullup resistor to get over this and-but the only provides mA max. If you are only trying to build a volt 2 amp power supply, there are better ways to do it in
