78SR100 Series
Very Small Footprint
High Efficiency > 85%
Self-Contained Inductor
Internal Short-Circuit Protection
Over-Temperature Protection
Wide Input Range
1.5 AMP POSITIVE STEP-DOWN INTEGRATED SWITCHING REGULATOR
The 78SR100 is a series of wide input voltage, 3-terminal Integrated Switching Regulators (ISRs). These ISRs have a maxi­mum 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 short­circuit and over-temperature protection, are very flexible, and may be used in a wide variety of applications.

The marketing status values are defined as follows:
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.

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)
