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.

The ISR will operate at no load with reduced specifications.
For operation below 0°C, use a tantalum type capacitor for C

.
See Thermal Derating curves.
The tab pins on the 5-pin mount package types (suffixes L & M) must be soldered. For more information see the applicable package outline drawing.

Note A:
Characteristic data has been developed from actual products tested at 25°C. This data is considered typical data for the Converter.
Note B:
Thermal derating graphs are developed in free-air convection cooling, which corresponds to approximately 40–60LFM of airflow.
