LMO78_0.5 Series

Wide Input Non-Isolated & Regulated, Single Positive/Negative Output

Switching Regulator

Eﬃciency up to 93%

Open frame SIP package

Ultra low no-load power

consumption

The LMO78_0.5A 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. This series is widely used in

industrial control, instrumentation, and electric power applications.

* Test ripple and noise by “parallel cable” method. With the load lower than 10%,

maximum ripple and noise will be 150mVp-p.

Note:

1. The max. capacitive load should be tested within the input voltage range and

under full load conditions;

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;

Model selection:

LMO78_yy-pp

4. All index testing methods in this datasheet are based on our Company’s

corporate standards;

LM=Series; S=case; ##=Vout; pp=output current

Example:

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;
