Frequently Asked Questions
Which input rail range is suitable for UA78L08CDE4 regulation?
UA78L08CDE4 is described with a 10.5 V to 23 V input operating range and 30 V absolute maximum input, so the upstream rail must stay within those limits.
How much output current can this fixed regulator support?
The fetched description identifies UA78L08CDE4 as a fixed 8 V positive linear regulator rated for 100 mA output current, suitable for modest bias and control rails.
What layout or assembly detail matters for the SOIC version?
The part is listed in an 8-pin SOIC package with JESD-30 code R-PDSO-G8, so PCB footprints and thermal assumptions should match that small-outline form.
When is UA78L08CDE4 preferable to a higher-current regulator?
It fits designs needing a simple fixed 8 V rail, 1.7 V nominal dropout, and 100 mA current rather than the larger package or cost of higher-current regulators.
