Specications subject to change without notice.
LMS78_0.5R Series
Wide Input Non-Isolated & Regulated, Single Positive/Negative Output
Typical application circuit
EMC solution-recommended circuit
To reduce the output ripple furtherly, it is suggested to connect a “LC” lter
at the output terminal, and recommended value of L is 10μH-47μH.
Part 􀀃1 in the Fig. 5 is for EMS test, part 2􀀃 is for EMI  ltering; parts 􀀃 and
􀀃 can be added based on actual requirement.
