9 Power Supply Recommendations

See Recommended Operating Conditions for the recommended power supply voltages for each variation of the

UA78L00. Note that each device variant may have a different recommended maximum operating voltage.

10 Layout

10.1 Layout Guidelines

Keep trace widths large enough to eliminate problematic I×R voltage drops at the input and output terminals.

Bypass capacitors should be placed as close to the UA78L00 as possible. Additional copper and vias connected

to ground facilitate additional thermal dissipation, preventing the device from reaching thermal overload.
