BIPOLAR LDO REGULATOR
5A BIPOLAR LINEAR REGULATOR
DESCRIPTION
FEATURES
Fixed and adjustable versions.
Maximum output current : 5A
A1084 is a series of low dropout three terminal
regulators with a typical dropout voltage of 1.4V at
5A load current.
Maximum input voltage: 15V
Line regulation: 0.2% (Typical)
Load regulation: 0.2% (Typical)
On-Chip Thermal Shutdown
Operation environment Temperature:
-40℃~ 85℃
Other than fixed voltage versions (1.8V, 2.5V, 3.3V,
5.0V), A1084 has an adjustable voltage version, with
which desired voltage can be achieved by setting the
values of two external resistors of the application
circuitry.
Available in TO-252, TO-263-2 and TO-263-3
packages
A1084 offers thermal shut down and current limit
functions to assure the stability of chip and power
system.
