GENERAL DESCRIPTION
The LND1086/LND1085 Series 1.5/3.0A fixed
and adjustable voltage regulators are monolithic
integrated circuits designed to power the new
generation of microprocessors for use in
applications requiring a well regulated positive
output voltage with low input-output differential
voltage requirements and output voltage 3.3, 2.9V
or 2.5V. Outstanding features include full power
usage up to 1.5/3.0A of load current, internal
current limiting and thermal shutdown. Other
fixed versions are also available V
4.0V. Please consult Linear Dimensions for more
information.
