Part Number: LM317 Other Parts Discussed in Thread: DAC80508 , TPS7B4255-Q1 Hello,
I would like to have some informations on this LM317.
The point of the project is to have on the input of the regulator 5V and to have an ouput between 1.5v and 5V…
Hi Tasneem,
How about using a tracking LDO, something like https://www.ti.com/product/TPS7B4255-Q1 , with a resistor + cap divider from VIN -> ADJ/EN -> GND?
It won't be a linear delay, but using a 20k resistor + 0.1uF cap for example should give…
Hi Zehui,
Yes , as long as the voltage provided at the ADJ/EN pin is within the recommended datasheet values, it does not matter if the voltage is provided by a dedicated voltage reference, MCU GPIO, battery, etc.
Just note that the LDO output will…
Hey Adrian,
This does not seem like a stability issue because the part is not oscillating.
This might be caused by the internal soft-start circuitry. The part could be starting up faster than the internal circuitry allows.
After speaking with colleagues…
What is the difference between a tracking LDO and a regular LDO?
A regular LDO reacts to changes in the input voltage, V IN and the load current, I OUT by dynamically minimizing error between the feedback voltage, V FB and an internal reference voltage…
