Hello guys. I am using LM338 regulator for my project. But when I build the circuit, the output voltage is equal to the input(I tried it on breadboard). There is no short circuit in the LM338 legs. The voltage is collected directly on R1 and the resistor gets very hot. There is no heating in...
Hello everyone,
I have attached a snip image of a design I am using and have been using for almost a year and a half now...
Here is the story on the board.
(Jump down to circuit explanation if you want)
Last year, I made a few hundred using the MP2357 regulator, but since it went out of...
Hi I need Help I’m trying to make a regulator that can take variable voltage from 30v to 100v ac input to about 15v dc output if any one can help point me in the right direction or have a circuit diagram that would be great
Hi all,
I feel like I am stuck because don't know how to solve following "simple" solution:
Somehow I have to (each 60 min) activate 12V/2A electromagnet, with 5V input voltage (tipical PC USB (5V/100mA).
5V is powering microcontroller, and with that microcontroller, each 60 min I have to...
I got a high voltage regulator (Discrete using BJTs)..Attaching the circuit..would like to calculate the biasing values how its been arrived..the load at Q2A switch from 0 and 1.3A..If any one can help on theoretical calculation would be helpful
Hi,
Does anyone have any good ideas how one could build a voltage divider that can actually deliver decent current (2-3A). The traditional resistor network would not work for obvious reasons.
I want to use this on my drone, the autopilot can take between a 3 and 6 cell battery but I want to...
Hey guys.
I'm designing a series pass voltage regulator with feedback. I'm trying to disconnect the load when the load current or control element temperature exceeds a value. The attached photos show my circuit design.
The temperature cutoff circuit works as is, but the current cutoff does...
