General Description
The APL1565A is a low dropout regulators operate
from 2.7V to 6V input voltage and deliver up to 1A
current capability. In order to obtain lower dropout
voltage and faster transient response, which is critical for low voltage applications, the APL1565/A has
been optimized.
The device is available in fixed output voltages of
2.5V,2.8V and 3.3V. APL1565A Dropout voltage is
guaranteed at a maximum of 210mV at 1A load.
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.
The APL1565A is available in the industry standard
8-pin SO power package which can be used in applications where space is limited.
