www.DataSheet4U.com rents
• Load Regulation : 0.6% Typ.
• Line Regulation : 0.03% Typ.
• Low Dropout Voltage : 1.3V Typ. at IOUT =500mA
• Current Limit : 0.8A Min. at TJ=125°C
• On-Chip Thermal Limiting : 150 °C Typ.
• Adjustable Output : 1.25~7.15V
• Standard 3-pin SOT-89, SOT-223,TO-92 and
TO-252 Power Packages.
The APL1087E 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 APL1087E 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 APL1087E is available in the industry standard
3-pin SOT-89, SOT-223,TO-92 and TO-252 power
packages.
