Features

General Description

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.
