APL1087
800mA Low Dropout Fast Response Positive Adjustable Regulator and Fixed
1.8V, 2.5V and 3.3V
Features
General Description
• Guaranteed Output Voltage Accuracy within 2% ^{The APL1087 is a low dropout three-terminal adjust-}
able regulators with 0.8A output current capability.
• Fast Transient Response
In order to obtain lower dropout voltage and faster
• Guaranteed Dropout Voltage at Multiple Cur-
rents
transient response, which is critical for low voltage
applications , the APL1087 has been optimized.
The device is available in an adjustable version and
• Load Regulation : 0.6% Typ.
• Line Regulation : 0.03% Typ.
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-
•
Low Dropout Voltage : 1.3V Typ. at I_OUT =500mA
teed at a maximum of 1.45V at 0.5A.
Current limit is trimmed to ensure specified output
• Current Limit : 0.8A Min. at T_J=125°C
current and controlled short-circuit current. On-chip
• On-Chip Thermal Limiting : 150 °C Typ.
• Adjustable Output : 1.25~7.15V
thermal limiting provides protection against any com-
bination of overload that would create excessive junc-
tion temperatures.
• Standard 3-pin SOT-89, SOT-223, TO-92 and
TO- 252 Power Packages.
The APL1087 is available in the industry standard 3-
pin SOT-89, SOT-223, TO-92 and TO-252 power
packages.
