the apl1087r is a low dropout three-terminal ad- justable 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 apl1087r has been optimized. the device is available in an adjustable version and fixed output voltages of 1.8v, 2.5v and 3.3v, the out- put available voltage range is from 1.25~7.15v with an input supply below 9v. dropout voltage is guaran- teed 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 com- bination of overload that would create excessive junc- tion temperatures. the apl1087r is available in the industry standard 3-pin sot-89 and to-92 power packages.

&$'( note 1: see thermal regulation specifications for changes in output voltage due to heating effects. load line regulations are mea- sured at a constant junction temperature by low duty cycle pulse testing. note 2: dropout voltage is specified over the full output current range of the device. dropout voltage is defined as the minimu m input/ output differential measured at the specified output current. test points and limits are also shown on the dropout voltage curv e. note 3: minimum load current is defined as the minimum output current required to maintain regulation.
