The APL1087R 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 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 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 APL1087R is available in the industry standard
3-pin SOT-89 and TO-92 power packages.

Electrical Characteristics (Cont.)

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 minimum input/

output differential measured at the specified output current. Test points and limits are also shown on the Dropout Voltage curve.

Note 3: Minimum load current is defined as the minimum output current required to maintain regulation.
