The EZ1587 series of high performance positive voltage

regulators are designed for use in applications requiring

low dropout performance at up to 3A. Additionally, the

EZ1587 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 EZ1587C is intended for commercial applications and

has both fixed and adjustable voltage options; the

EZ1587I is intended for industrial applications and is

adjustable only.

All devices are available in the popular TO-220 and

TO-263 packages.
