FAN1587AMCX is a type of three-terminal regulator with low dropout and 3A output current capability. It is specifically designed for low-voltage applications requiring transient response and minimum input voltage. Moreover, it is able to provide optimum performance for low-voltage microprocessor applications where a regulated output from 1.5V to 3.6V with an input supply of 12V or less is critical. Specified output current and controlled short-circuit current can be ensured due to the current limit being trimmed.
