APL1085
3A Low Dropout Fast Response Positive Adjustable Regulator and Fixed 3.3V
Features
General Description
•
•
The APL1085 is a low dropout three-terminal adjustable regulator with 3A output current capability. In
order to obtain 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 1.25~5.75V with an input supply below 7V ,
and the fixed 3.3V output voltage device is also
available.

Load Regulation : 0.05% Typ.
Line Regulation : 0.03% Typ.
Low Dropout Voltage : 1.2V Typ. at IOUT =3A
Trimmed Current Limit : 3A Typ. at TJ=125 °C
Current limit is trimmed to ensure specified output
current and controlled short-circuit current. On-chip
thermal limiting provides protection against any combination of overload that would create excessive junction temperatures.
On-Chip Thermal Limiting : 150 °C Typ.
Standard 3-pin TO-220 , TO-252 and TO-263
Power Package
The APL1085 is available in both the through-hole
and surface mount versions of the industry standard
