LMS78_1.5-1.5 数据手册

LMS78_1.5 Series

Wide Input Non-Isolated & Regulated, Single Output

Switching Regulator

Efﬁciency up to 95%, no

heatsink required

1.5A large current output

Operating temperature:

-40°C ~ +85°C

Short circuit protection,

thermal shutdown

Micro miniature SIP package,

meet UL94-V0 requirement

Ultra low power loss

Industry standard pinout

Pin-out compatible with

LM78XX Linear

Upgraded LMS78_1.5 series switching regulators are ideal replacement

for LM78xx linear regulators and LDOs. The efﬁciency of up to 95%

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

heat sinks with their additional space and mounting costs. They are

widely used in industrial control, instrumentation, and electric power

applications.

MTBE>2000,000Hours

Low ripple and noise

Model selection:

LMS78_yy-pp

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

Example:

LMS78_05-1.5

LM=Series; S=SIP Case; ##= 5Vout; pp=1.5A
