1-A Positive Step-down
Integrated Switching Regulator
Description
The PT5100 modules are a series of
economical, easy-to-use 1-A positive
step-down, Integrated Switching Regulators (ISRs). These ISRs are compatible
with most TO-220 style linear regulators,
and when employed as a linear replacement, 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 marketing status values are defined as follows:
13-Oct-2005
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in
a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS) or Green (RoHS & no Sb/Br) - please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
