Post Regulator for Switching Power Supply

The APL1085 is a low dropout three-terminal adjustable

regulator with 3A output current capability. In order to ob-

tain lower dropout voltage and faster transient response

which is critical for low voltage applications, the APL1085

has been optimized. The output available voltage range

of adjustable version is from 1.25 to 5.75V with an input

supply below 7V, and the fixed 3.3V output voltage device

is also available.

Current limit is trimmed to ensure specified output cur-

rent and controlled short-circuit current. On-chip thermal

limiting provides protection against any combination of

o ve r l o a d t h a t wo u l d c r e a t e e xc e s s i ve j u n c t i o n

temperatures.

The APL1085 is available in both the through-hole and

surface mount versions of the industry standard 3-pin

TO-220,TO-252, and TO-263 power packages.
