description/ordering information
This
series
of
fixed
negative-voltage
OUTPUT
integrated-circuit voltage regulators is designed
for a wide range of applications. These include
on-card regulation for elimination of noise and
distribution problems associated with single-point
INPUT
COMMON
regulation. In addition, they can be used to control series pass elements to make high-current voltage-regulator
circuits. One of these regulators can deliver up to 100 mA of output current. The internal current-limiting and
thermal-shutdown features essentially make the regulators immune to overload. When used as a replacement
for a Zener-diode and resistor combination, these devices can provide an effective improvement in output
impedance of two orders of magnitude, with lower bias current.

-
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)
(3)
MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder
