Note:
1. The max. capacitive load should be tested within the input voltage range and
under full load conditions;
* Test ripple and noise by “parallel cable” method. With the load lower than 10%,
maximum ripple and noise will be 150mVp-p.
2. Without any special statement, all indexes are only specific to positive output
application;
3. Unless otherwise specified, data in this datasheet should be tested under the
conditions of Ta = 25°C, humidity <75% when inputting nominal voltage and
outputting rated load;
4. All index testing methods in this datasheet are based on our Company’s
corporate standards;
Example:
LMS78_05-0.5R
LM = Series; S = SIP Case; 05 = 5Vout; 0.5 = 0.5A; R = Revised
5. The performance indexes of the product models listed in this manual are as
above, but some indexes of non-standard model products will exceed the
above-mentioned requirements, and please directly contact with our technician
for specific information;
6. Specifications subject to change without prior notice.

Note:
Part number
C1,C3
(Ceramic Capacitor)
C2,C4
(Ceramic Capacitor)
1. C1 and C2 are required and should be connected close to the pin terminal
of the module.
2. The capacitance of C1 and C2 refer to Sheet 1, it can be increased properly
if required, and tantalum or low ESR electrolytic capacitors may also
suffice.
3. When the products used as the circuit like figure 3, an inductor named as
LDM up to 10μH is recommended in the circuit to reduce the mutual
interference.
4. Cannot be used in parallel for output and hot swap.
5. Operation under no load will not damage these devices, however they may
not meet all specifications. In order to ensure the converter can work
reliably with high efficiency, please parallel a resistor on the output side
(The sum of the efficient power and resistor consumption power is not less
than 10%).

LMS78_0.5R Series
Wide Input Non-Isolated & Regulated, Single Positive/Negative Output
Typical application circuit
To reduce the output ripple furtherly, it is suggested to connect a “LC” filter
at the output terminal, and recommended value of L is 10μH-47μH.
EMC solution-recommended circuit
Part 1 in the Fig. 5 is for EMS test, part 2 is for EMI filtering; parts
can be added based on actual requirement.
