Since the regulator is.

Lmhv datasheet, cross reference, circuit and application notes in pdf format. That is why in the application images it shows a output of 50 volts with an input of 60 volts or less. Is this for a bench supply of some kind?

In a word – NO. You can follow the App Notesdatasheet but remember if the input short circuits for any reason the chip must be om317hv with a reverse diode. The lm lm lm family of adjustable 3terminal positive voltage regulators can take a input of 3 to 40 volts dc and provide a regulated voltage over a 1. Satasheet, the LMHV is packaged in standard transistor packages which are easily mounted and handled.

Also, what should be the power ratings of the resistors R5 and R4.

Second, in case of output overload, voltage drop across LM may become as high as Vin, which will breake it. It is possible but not this way.

National Semiconductor Lj317hv Components Datasheet. Normally, no capacitors are needed unless the device is situ- ated more than 6 inches from the input filter capacitors in which case an input bypass is needed.

If so, is there anything that I have to be careful such as power ratings, Vmax, Vce, etc. Below is an ‘Active’ zener diode using a bjt to boost the load current. Post as a guest Name. Full output current not available at high input-output voltages. Why not buy a PSU from Meanwell? Email Required, but never shown. Besides replacing fixed regulators, the LMHV is useful in a wide variety of other applications.

It requires only two external resistors to set the output datqsheet.

The lmhvlmhv are adjustable 3terminal or by connecting a fixed resistor between the positive voltage regulators capable of supplying in adjustment and output, the lmhv can be used as excess of 1.

This is a limit set forth in section 6. Use caps rated for Vin and Vout, and connect them directly. There is a switching circuit at the tail of the regulator that charges and discharges the piezo actuator. Here is the datasheet: I am going to drive a piezo actuator with this.

They are exceptionally easy to use and require only two external resistors to set the output voltage.

But a phase controlled triac or variac supply will drop from no load to full load depends on Pd wasted power and Vmin for LDO so power is a premium for rep rate of datasehet. C2 could be a problem too. Lmhv lmhv 3terminal adjustable regulator kbytes 14apr00 view online download receive via email if you have trouble printing or viewing pdf files, see printing problems.

Could you help me to calculate the required power rating? Above circuit diagram is a easy, simple and cheap switching voltage regulator which has capability to deliver adjustable voltage output range of 1.

First, zener in series with capacitor C1 and C3, datasheer shown in EDIT2 will not work – where is no path for discharge current until voltage of “-” pin drops to zero. Eatasheet can I add some extra protection to limit the current demand of the load? Or are you trying to power a Nixie?

You can use a beefy zener diode to raise ground up volts or more, but this becomes your new ‘ground’ reference and if it shorts the LM will short out as well.
