PT78ST100 Series

1.5 Amp Positive Step-Down

Integrated Switching Regulator

SLTS059A

(Revised 6/30/2000)

•

Very Small Footprint

These ISRs have a maximum output current

of 1.5 Amps and an output voltage that is laser

trimmed to a variety of industry standard volt-

ages.

These 78 series regulators have excel-

lent line and load regulation with internal

short- circuit and over-temperature protec-

tion, and are offered in a variety of standard

output voltages. These ISRs are very flex-

ible and may be used in a wide variety of

applications.

High Efficiency > 85%

Self-Contained Inductor

Internal Short-Circuit Protection

Over-Temperature Protection

Fast Transient Response

Wide Input Range

The PT78ST100 is a series of wide-

input range, 3-terminal regulators.

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)
