1.5 AMP POSITIVE STEP-DOWN

INTEGRATED SWITCHING REGULATOR

Revised 6/30/98

The 78SR100 is a series of wide input

•

Very Small Footprint

High Efficiency > 85%

Self-Contained Inductor

Internal Short-Circuit Protection

Over-Temperature Protection

Wide Input Range

voltage, 3-terminal Integrated Switching

Regulators (ISRs). These ISRs have a maxi-

mum output current of 1.5A and an output

voltage that is laser trimmed to a variety of

industry standard voltages.

These 78 series regulators have excellent

line and load regulation with internal short-

circuit and over-temperature protection, are

very flexible, and may be used in a wide

variety of applications.

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)

(3)

MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder

temperature.
