GENERAL DESCRIPTION
The CM1084 series of high performance positive voltage
regulators are designed for use in applications requiring low
dropout performance at full rated current. Additionally, the
CM1084 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 CM1084 series are three terminal regulators
with adjustable voltage options available in popular
packages.
