CM1085
3.0 AMP POSITIVE VOLTAGE REGULATOR
GENERAL DESCRIPTION
FEATURES
The CM1085 series of high performance positive voltage
regulators are designed for use in applications requiring low
dropout performance at full rated current. Additionally, the
CM1085 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 CM1085 series are three terminal regulators !
with adjustable voltage options available in popular
packages.
