I have tried to use several LT1763 (5.V, 3.3V and 2.5V) and could never get them to work properly. I am using a 10nF ceramic capacitor as Bypass, a 1uF electrolytic on the input side and a 10uF electrolytic on the output side.
I have a situation in a circuit that for a time period of approximately lessthan 10msec linear regulator input pin of LT1763 is subjected to 25V peak or greater than 20V which is greater than its absolute maximum.
I want to use the LT1763IS8-1.8 chip to convert +5V to 1.8V. The schematic and PCB are as follows, but in the actual circuit, the output of the 1-pin is measured by a multimeter to be 2.1V, and the +5V input is also reduced to 4.5V. Why, what should…
to obtain 3,3V output voltage with your configuration you need to buy the fixed 3.3V version. If you install the adjustable LT1763 in your board the output will be equal the ref voltage=1.22V. Both feature different top markings
