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.

Pin-out compatible with

LM78XX Linear

Meets EN62368 standards
