DESCRITION

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.
