Safety Precaution
WARNING
Service should not be attempted by anyone unfamiliar with the necessary precautions on this
monitor.
The followings are the necessary precautions to be observed before servicing.
1. When managing this monitor, cover with shield plate to avoid to scrach on LCD surface.
. When replacing a chassis in the cabinet, always be certain that all the protective devices are
put back in place, such as nonmetallic control knobs, insulating covers, shields, isolation
resistor capacitor network etc.
3. Before returning the monitor to the customer, always perform an AC leakage current check
on the exposed metallic parts of the cabinet, such as signal connectors, terminals, screw
heads, metal overlays, control shafts etc, to be sure the monitor is safe to operate without
danger of electrical shock.

Description
The RC1117 and RC1117-2.5, -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.
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 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 RC1117 flows into the load, increasing efficiency.
The RC1117 series regulators are available in the industry-
standard SOT-223, TO-263 (D2PAK), and TO-252 (DPAK)
power packages.

Notes:
1. See thermal regulation specifications for changes in output voltage due to heating effects. Load and line regulation are
measured at a constant junction temperature by low duty cycle pulse testing.
2. Line and load regulation are guaranteed up to the maximum power dissipation (18W). Power dissipation is determined by
