APL1541 Datasheet | Anpec Electronics Coropration

Features - - - .. General Description The APL1541 is a low dropout three-terminal adjustable regulators with 1A output current capability. In order to obtain lower dropout voltage and faster transient response, which is critical for low voltage applications , 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 supply 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 bination of overload that would create excessive junction temperatures. The APL1541 is available in the industry standard 8pin SO power package which can be used in applications where space is limited.
