AMS1117
1A Adjustable/Fixed Low Dropout Linear Regulator
General 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 cur-
rent of the
AMS1117
flows into the load, increasing effi-
ciency.
The
AMS1117
series regulators are available in the indus-
try-standard SOT-223 and TO-252 power packages.
