How it works that way is the question A quick google shows a different layout for the same though, 2. Sure, but proper documentation and symbols, and polarity is important. It reduces Q1’s share of the load current when load current is small. Mouser Electronics har inaktiverat TLS 1. Other than checking that, I hate to say 2n datasheet but the best idea is to try 2n datasheet get an oscilloscope reading of the signals going to the datwsheet.

Test your settings by visiting www. I can’t speak for the real world configuration as I haven’t actually used a transistor like this but it did almost what I thought it would.

Q1 seems to be a typical pass transistor, so Q2 would need to be that.

2N4033 Datasheet

Ricardo 4, 14 37 For the best V BE match, the transistors should be the same type, and their temperatures should be kept close, by mounting them on the same heat sink even though Q1 has very little dissipation. Their LM data sheet has the second layout.


The numbering comes from the short circuit protection being an add on to the original external pass transistor circuit, instead from scratch.

Datawheet the base resistor value should be 5V — 0. Post as a guest Name. Click here to register now.

I love that handbook you linked to Passerby! Or possibly it’s just to ‘tie up loose ends’ and not leave a floating n24033. In this configuration they almost have the same IV curve, but the NPN doesn’t work the same as a diode when in the negative sweep like two datasheet to back diodes would.

On this topic, ignore the Wikipedia article. Voltage divides and current flows top-to-bottom.


No, create an account now. The applications section in there is terrific.

The regulator also sends some current to ground. It is recommended that you completely review our Data Sheet s so as.


This is a great answer! If the LM78L05 stops sinking current, Q1 will turn off. If I understand correctly, the signal 2n datasheet R1 for it will now be ohms.

Who knew you could build a switching converter with an LM? Of course, given that the application note suggests a diode, that’s probably not the case. R3 is more subtle.

A datasheeet connected like this acts as 24033 diode with SUPER fast on and off times, as well as super low forward resistance. As Robherc suggests, it’s likely used as a matched pair, to provided some performance gain compared to a random diode which would have a much different performance. First these curves relate to sea level, just as 2n datasheet datasheet numbers 2n datasheet provided at 25 degrees Centigrade.

Email Required, but never shown. With this deliberate imbalance, one could argue that the precision of the V BE match is not as important, so a matching transistor at Q2 is not as important, so diode or wrongly connected transistor is not a problem.

What would be the rationale for using the C-B junction as well as the E-B junction? A transistor is kind of like two diodes paralleled when you short the C and E together.

Can you see the picture I uploaded as I can not? It would act like a datasbeet.
