CX1084
5A Low dropout voltage regulator
GENERAL DESCRIPTION
The CX1084 series of adjustable and fixed voltage regulators are designed to provide 5A output
current and to operate down to 1V input-to-output differential. The dropout voltage of the device is
guaranteed maximum 1.5V at maximum output current, decreasing at lower load currents.
On-chip trimming adjusts the reference voltage to 1%. Current limit is also trimmed, minimizing the
stress under overload conditions on both the regulator and power source circuitry.
The CX1084 devices are pin compatible with older three-terminal regulators and are offered in 3 lead
TO-220,2 lead TO-252 package and 3 and 2 lead TO-263 (Plastic DD).
