DESCRIPTION
FEATURES
The EZ1087 5.0A voltage regulator is a monolithic
integrated circuit designed for use in applications
requiring a well regulated positive output voltage with
low input-output differential voltage requirements and
where remote sensing of the output voltage is desired
to compensate for connector, wiring and pc board
trace resistances or other voltage losses. Other
outstanding features include full power usage up to
5.0A of load current, internal current limiting, and
thermal shutdown. Specifications guarantee 3.30 VDC
output from a 4.75 VDC input.
•= Low dropout performance, 1.3V max.
•= Kelvin remote sense inputs
•= Line regulation typically 0.015%
•= Load regulation typically 0.1%
•= 5-pin TO-220 package
