LMW78_0.5 Series

Wide Input Non-Isolated & Regulated, Single Output

Switching Regulator

Eﬃciency up to 95%

Ultra wide input voltage

range can up to 8:1

Operating temperature:

-40°C ~ +85°C

Pin-out compatible with

LM78XX Linear

Short circuit protection (SCP),

The LMW78_0.5 series high eﬃciency switching regulators are ideally

suited to replace LM78xx linear regulators and are pin compatible. It

has ultra wide input voltage range, the eﬃciency of up to 95% means

that very little energy is wasted as heat so there is no need for any

heatsinks with their additional space and mounting costs.

thermal shutdown

Low ripple and noise

Micro miniature SIP package,

meet UL94-V0 requirement

No heatsink required

Industry standard pinout

MTBF>2,000,000Hours

Model selection:

LMW78_yy-pp

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

Example:

LMW78_05-0.5

LM=Series; W=wide input; ##= 5Vout; pp=0.5A

1. The load shouldn‘t be less than 10%, and the output external capacitor should

not be too large (recommend <10μF), otherwise ripple will increase

dramatically.
