APL1087

APL1087 800mA Low Dropout Fast Response Positive Adjustable Regulator and Fixed 1.8V, 2.5V and 3.3V Features www.DataSheet4U.com General Description The APL1087 is a low dropout three-terminal adjustable regulators with 0.8A output current capability. In order to obtain lower dropout voltage and faster transient response, which is critical for low voltage applications , the APL1087 has been optimized. The device is available in an adjustable version and fixed output voltages of 1.8V, 2.5V and 3.3V, the output available voltage range is from 1.25~7.15V with an input supply below 9V. Dropout voltage is guaranteed at a maximum of 1.45V at 0.5A. 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 APL1087 is available in the industry standard 3pin SOT-89, SOT-223, TO-92 and TO-252 power packages.
