General Description

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.
