EZ1117/EZ1117A
POWER MANAGEMENT
Description
The EZ1117 series of high performance positive voltage
regulators are designed for use in applications requiring
low dropout performance at full rated current.
Additionally, the EZ1117 series provides excellent
regulation over variations in line, load and temperature.
Outstanding features include low dropout performance
at rated current, fast transient response, internal current
limiting and thermal shutdown protection of the output
device. The EZ1117 series of three terminal regulators
offer
fi
xed and adjustable voltage options available in
the space saving SOT-223 and TO-263 packages.
