linear regulator

Hello everyone, I am new to electronics and I am currently designing a linear regulator using the LT1575 Controller. Could someone please assist me in determining the value of RLIM for current protection?

Hello all, This is my first post so forgive me if I break any rules, I am trying to create a variable voltage power supply using an lm317 but am running into problems. For starters, it doesn't seem that I have a vref voltage, when probed I get 0 volts across input and adjust. My second problem...

Here a shunt voltage regulator circuit with two zener diodes One zener diode Z give the reference voltage at the comparator for the feedback signal . But I can't explain the role of the second zener diode Z1 I've to calculate Voltage Stability factor (Sv) . Any Suggestion is welcome.

Hello, I need to design a linear regulated supply to power an dac output stage based on op amp. It must be a negative + ground + positive one. The problem I encounter is that I don't know wich topology to select between the first and second arrangement. I suppose that the first one induce a...

Hello, I am fairly new to electronics design (I have a mech e background), and am designing a board that requires dropping 12v to 5v with a large current requirement (up to 8A@5V). In a bid to save on BOM, I took a shot at creating my own design vs buying one off the shelf, using the...
