ETC CM1084KCN220 5.0 amp positive voltage regulator Datasheet

CM1084
5.0 AMP POSITIVE VOLTAGE REGULATOR
GENERAL DESCRIPTION
FEATURES
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.
Low dropout performance
1.3V max. for CM1084
Full current rating over line and temperature
Fast transient response
!
±2% total output regulation over line, load and temperature
!
Adjust pin current max 90µA over temperature
Outstanding features include low dropout performance at
!
Adjustable output voltage
rated current, fast transient response, internal current
!
Line regulation typically 0.015%
limiting and thermal shutdown protection of the output
!
Load regulation typically 0.1%
device. The CM1084 series are three terminal regulators
!
TO-220, TO-252 and TO-263 packages
with adjustable voltage options available in popular
packages.
