Note:
1. The max. capacitive load should be tested within the input voltage range and
under full load conditions;
Example:
LMS78_05-1.0RL
2. Without any special statement, all indexes are only specific to positive output
application;
LM = Series; S = SIP Case; 05 = 5Vout; 1.0 = 1.0A; R = Revised;
L = Bended Pins
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;
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
