Outline：

BL1084 is a series of low dropout three

terminal regulators with a dropout of 1.4V at

5A load current.

Other than a fixed version (Vout ＝

1.8V,2.5V,3.3V,5.0V ） , BL1084 has an

adjustable version, The adjustable version can

set the output voltage with two external

resistors.

BL1084 offers thermal shut down and current

limit functions, to assure the stability

of chip and power system.

The BL1084 series is available in standard

packages of TO-263-2L, TO-263-3L, TO-220

and TO-252.
