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.
