FeaturesGeneral Description

The APL1087 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 APL1087 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 avail-

able voltage range is from 1.25 to 7.15V with an input

supply below 9V. Dropout voltage is guaranteed at a maxi-

mum of 1.45V at 0.5A.

Current limit is trimmed to ensure specified output cur-

rent and controlled short-circuit current. On-chip thermal

limiting provides protection against any combination of

overload that would create excessive junction

temperatures.

The APL1087 is available in the industry standard 3-pin

SOT-89, SOT-223, TO-92, and TO-252 power packages.

Applications

• Voltage Regulator for CD-ROM Drivers

• Voltage Regulator for LAN Cards

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.

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.

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