General Description
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.
Applications
Voltage Regulator for CD-ROM Drivers
Voltage Regulator for LAN Cards
