LMO78_1.0 Series  
Wide Input Non-Isolated & Regulated, Single Positive/Negative Output  
Switching Regulator  
High efficiency up to 96%  
Operating temperature  
range: -40°C ~ +85°C  
Open frame SIP package

standards  
The LMO78_1.0 series is a high efficiency switching regulator and ideal  
substitute for the LM78xx series three-terminal linear regulators. The  
product is featured with high efficiency, low loss, short circuit  
protection and no heat sink is required. They are widely used in indust-  
rial control, instrumentation, and electric power applications.

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 20%,  
the maximum ripple and noise of 3.3V/5V output products will be 100mVp-p,  
12V/15V output products will be 2%Vo.  
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;  
Example:  
4. All index testing methods in this datasheet are based on our Company’s  
corporate standards;  
LMO78_05-1.0  
LM = Series; S = SIP Case; 05 = 5Vout; 1.0 = 1.0A  
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;

1. C1 and C2 (C3 and C4) are required and should be connected close to the  
pin terminal of the module.  
2. The capacitance of C1 and C2 (C3 and C4) refer to table on the left.  
3. To reduce the output ripple furtherly. C2 and C4 can be increased properly  
if required, and tantalum or low ESR electrolytic capacitors may also  
suffice.  
4. When the products are used as shown in the „positive and negative output  
paralleling application circuit“, an inductor named as LDM up to 10μH is  
recommended in the circuit to reduce the mutual interference.  
5. Cannot be used in parallel for output and hot swap.
