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

Note:
1. C1 and C2 are required and should be fitted close to the converter pins.
2. The capacitance of C1and C2 sees external capacitor table, it can be
increased properly if required, and tantalum or low ESR electrolytic capacitors
may also suffice.
3. No parallel connection or plug and play.
