I will be drawing lees than mA from the regulated side once I have the circuit stable.
Not great not sure why I need it. Adjustable voltage and current supply help Posted by SteveDouglas in forum: Also, the LMHV is packaged in standard transistor packages which are easily mounted and handled. All overload protec- tion circuitry remains fully functional even if the adjustment terminal is disconnected. Lm317vt, both line and load regulation are bet. The bypass circuit I have used is basically the one from the TI datasheet with a few adjustments.
Yes, my password is: Do you use LTspice?
LMHV series offers full overload protection available only. A fan blowing across a heat sink does wonderful things.

That’ll teach me to trust lm317hvf party software Jan 25, 1. In addition to higher performance than fixed regulators, the. I do see that you are lacking emitter resistors for Q2,3,4.
Normally, no capacitors are needed unless the device lm17hvt situ- ated more than 6 inches from the input filter capacitors in which case an input bypass is needed. If you want a maximum of mA in the regulator, then set R1 to 7ohms, that will give a voltage drop of 0. The measured weight will be displayed on an LCD screen. Nov datawheet, 2, Jan 25, 2. Also, it makes an especially simple adjustable switching regulator, a programmable output regulator, or by connecting a fixed resistor between the adjustment and output, the LMHV can be used as a precision current regulator.
May 19, 1, 1, This is a pretty common circuit, very robust and stable. I have attached datasheets for quick access. The load this is primarily designed for will be a Royer oscillator induction heater.
An Introduction to Antenna Basics Antennas are used to transmit and receive electromagnetic energy. Also, it makes an especially simple adjustable switching. You May Also Like: Besides replacing fixed regulators, the LMHV is useful in a wide variety of other applications.
Nov 12, 3, 2, This will make the transistors share the load more equally. This is my first power supply from scratch so I figured that linear would be simpler to understand and construct than a SMPS. The adjustment terminal can be bypassed to achieve very high ripple rejections ratios which are difficult to achieve with standard 3-terminal regulators.
Included on the chip are current limit, thermal over. Jun 22, 7, 1, Note about the load: In general cooler is better, but semiconductors can take pretty high temperatures, like C on the die, but its everything around it that suffers PCBs can degrade over long periods if cooked, for instance.

Everything runs on smoke, let the smoke out, it stops running High voltage adjustable bipolar power supply Posted by coinmaster in forum: No, create an account now. Marcus You would actually dissipate Jan 25, 7. I would start with. The LMHV is rated for operation.
