1.4V max. for EZ1086I, 1.45V max. for EZ1086BC

temperature (±2.4% for EZ1086BC)

DESCRIPTION

The EZ1086 series of high performance positive

voltage regulators are designed for use in applications

requiring low dropout performance at full rated current.

Additionally, the EZ1086 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.

A variety of options are available for maximum

flexibility: the EZ1086C has both fixed and adjustable

voltage options and is designed for use in commercial

applications; the EZ1086BC is adjustable only for cost

sensitive commercial applications; the EZ1086I is

adjustable only for industrial applications. All devices

are available in the popular TO-220 and TO-263

packages.
