RS1117A
1.0A Low Dropout Positive Voltage Regulator
Page No. : 1/13
General Description
The RS1117A is a 1A low‐dropout positive voltage regulator. It is available in fixed and adjustable output voltage versions.
Over current and thermal protection are integrated onto the chip. Output current will limit as while it reaches the pre‐set
current or temperature limit. The dropout voltage is specified at 1.40V Maximum at full rated output current. The RS1117A
series provides excellent regulation over line, load and temperature variations.
Features
● Low Dropout Voltage 1.40V (Max.) at 1.0A
● Adjustable or Fixed Voltage (1.2V, 1.8V, 2.5V, 3.3V and
5.0V)
● Over Current Protection
● Thermal Overload Protection
● Maximum Line Regulation 0.2%
● Maximum Load Regulation 1.0%
● Adjust Pin Current Less Than 120uA
Applications
● SCSI‐2 Active Termination
● High Efficiency Linear Regulators
● 5V to 3.3V Voltage Converter
● Battery Charger
● Battery Management Circuits For Notebook And
Palmtop PCs
● Core Voltage Supply: FPGA, PLD, DSP, CPU
Application Circuits
This integrated circuit can be damaged by ESD. Orister Corporation recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
