IC Integrated Circuit of 1A Adjustable/Fixed Low Dropout Linear Regulator AMS1117-2.5

Product Description

1A LOW DROPOUT VOLTAGE REGULATOR
 
Description
The AMS1117-ADJ and AMS1117-1.2,-1.5,-1.8,-2.5,-2.85,
-3.3 and-5 are low dropout three-terminal regulators with
1A output current capability. These devices have been
optimized for low voltage where transient response and
minimum input voltage are critical. The 2.85V version is
designed specifically to be used in Active Terminators for
SCSI bus.
On-chip thermal limiting provides protection against any
combination of overload and ambient temperatures that
would create excessive junction temperatures.
Unlike PNP type regulators where up to 10% of the output
current is wasted as quiescent current, the quiescent current
of the AMS1117 flows into the load, increasing efficiency.
 
The AMS1117 series regulators are available in the industry-standard
SOT-223 and TO-252 power packages.
