BFT66,Philips | IC Chips |
Unfortunately, the low noise of the JFET derives from low input current, hence a high input resistance some MOhm is necessary. Distorted Sine output from Transformer 8.
Nominal zener voltage 62V. From a power supply manufacturer I read some email correspondence with TI tech support where he also claimed more drift in recent parts. The Infineon’s app note suggests that the best oscillator transistor is a device with the lowest possible fT. How do you get an MCU design to market quickly?
Nominal zener voltage 19V. So, in case you have decided for an LM to make a good power supply, there are some rules of thumb that will make your life easier:. Equating complex number interms of the other 6.
If you want precision current control, dont try to do this with a pot sampling a fraction of voltage across a shunt measurement resistor. Before you specify a compensation cap, run a few tests using SPICE to see if gain and phase margins are in order. CMOS Technology file 1.
Input voltage goes up tp 40V constant, with 50V pulses allowed. Provide enough voltage headroom. There are only better ones with low voltage 10V and less datashet, and they cost a lot more than a LM Click here for a larger resolution picture … A lot of basic application circuits can be found in the LM datasheet.
HF transistor BFT66 TO72
Error amp bias current. Nominal zener voltage 87V. Oscillator phase noise 1. The net and some manufacturers application notes are also a good source of information.
BFT66 Datasheet, Equivalent, Cross Reference Search
Nominal zener voltage 4. Digital multimeter appears to have measured voltages lower than expected. Nominal zener voltage 22V.
Try with different output voltages, load currents and input voltages. Nominal zener voltage 25V. This also acts as a soft start feature. They see this chip as an old-age part that has no merits today.
Its comparing apples and oranges. This cancels the error amps base bias currents.

The performance of an LM is not bad at all, especially for noise and long term stability. Nominal zener voltage 14V.
Nominal zener voltage 30V. The LM values translate to about 0. Tempco is also very good, also when compared to newer chips. Part and Inventory Search. For low noise crystal eatasheetdepending on the frequency, a FET or a BIP transistor with the right size, fT and proper bias condition should be selected.
