LME78_05-1.0 数据手册

LME78_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

Short circuit protection (SCP)

No-load input current as low

as 0.3mA

3PIN SIP package

The LME78_1.0 are high eﬃciency switching regulators and ideal

substitutes of LM78xx series three-terminal linear regulators. The

product is featured with high eﬃciency, low loss, short circuit protection

and no heat sink requirement. They are widely used in industrial control,

instrumentation, and electric power applications.

Non isolated, no need for

heatsink

* 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, 9V/12V/15V output products will be 2%Vo.
