LMS78_2.0R Series

Wide Input Non-Isolated & Regulated, Single Output

Switching Regulator

Operating temperature:

-40°C ~ +85°C

Short circuit protection

No-load input current as low

as 0.1mA

Eﬃciency up to 95%

The LMS78_2.0R series are high eﬃciency switching regulators and ideal

substitutes of LM78xx series three-terminal linear regulators. The

product is featured with high eﬃciency, low loss and no heat sink requi-

rement. They are widely used in industrial control, instrumentation,

and electric power applications.

Note:

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.

3. To reduce the output ripple furtherly, C2 can be increased properly if required, tantalum

capacitor and aluminum electrolytic capacitor of low ESR may also suﬃce.

4. Cannot be used in parallel to enlarge the power for output and hot swap.
