Standard Application
Description
The PT5100 modules are a series of
economical, easy-to-use 1-A positive
step-down, Integrated Switching Regu-
lators (ISRs). These ISRs are compatible
with most TO-220 style linear regulators,
and when employed as a linear replace-
ment, provide significant benefits in
both efficiency and power dissipation.
They are recommended for use in a wide
variety of on-board power regulation
applications. These include computer,
data storage, industrial controls, and
battery powered equipment. Modules
are laser-trimmed for optimal output
voltage accuracy, and exhibit excellent
line and load regulation. The PT5100
also features output current limiting
and thermal shutdown protection.
