The APL1541 is a low dropout three-terminal adjust-
able regulators with 1A output current capability. In
order to obtain lower dropout voltage and faster tran-
sient response, which is critical for low voltage ap-
plications , the APL1541 has been optimized.
The device is available in an adjustable version and
fixed output voltages of 3.3V, the output available
voltage range is from 1.25~7.75V with an input sup-
ply below 12V. Dropout voltage is guaranteed at a
maximum of 1.3V at 1A.
Current limit is trimmed to ensure specified output
current and controlled short-circuit current. On-chip
thermal limiting provides protection against any com-
bination of overload that would create excessive junc-
tion temperatures.
The APL1541 is available in the industry standard 8-
pin SO power package which can be used in appli-
cations where space is limited.
