ST1117
■DESCRIPTION
The ST1117 is a positive low dropout voltage
regulators with 1A output current capability.
In order to obtain lower dropout voltage and fast
transient response, which is critical for low voltage
application. The ST1117 has been optimized. The
device is available in an adjustable version and
fixed output voltage of 1.8V, 2.5V, 3.3V and 5V.
Dropout voltage is guaranteed at a maximum of
1.3V at 1A.
Current limit is trimmed to ensure specified output
current and controlled short circuit current. On-chip
thermal limiting provides protection against any
combination of overload that would creat excessive
junction temperatures.
The ST1117 is aviliable in the SOT-223 and
surface mount packages.
