The APL1187 is a low dropout three-terminal adjustable

regulators with 0.6A output current capability. In order to

obtain lower dropout voltage and faster transient

response, which is critical for low voltage applications,

the APL1187 has been optimized.

The device is available in 1.2V with an input supply below

9V. Dropout voltage is guaranteed at a maximum of 1.55V

at 0.6A.

Current limit is trimmed to ensure specified output current

and controlled short-circuit current. On-chip thermal

limiting provides protection against any combination of

o ve r l o a d t h a t wo u l d c r e a t e e xc e s s i v e j u n c t i o n

temperatures.

The APL1187 is available in the industry standard 3-pin,

SOT-89 and SOT-223 package.
