Description

ACE1084 is a series of low dropout three terminal regulators with a typical dropout voltage of 1.4V at

5A load current.

Other than fixed voltage versions (1.8V, 2.5V, 3.3V, 5.0V), ACE1084 has an adjustable voltage version,

with which desired voltage can be achieved by setting the values of two external resistors of the

application circuitry.

ACE1084 offers thermal shut down and current limit functions to assure the stability of chip and power

system.

ACE1084 series is available in standard packages of TO-263-2L, TO-263-3L, TO-220 and TO-252.
