Description
Features
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.
Low dropout voltage: 1.3V max. for EZ1587C and
1.4V max. for EZ1587I
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
Fixed/adjustable output voltage (EZ1587C)
Line regulation typically 0.015%
Load regulation typically 0.05%
Industrial temperature range (EZ1587I)
TO-220 and TO-263 packages. Available in RoHS
compliant package
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.
Applications
Printer and plotter supplies

Pin Name Pin Function
1
ADJUST
This pin is the negative side of the reference voltage for adjustable devices. Transient response
can be improved by adding a small bypass capacitor from the adjust pin to ground.
GROUND
This pin is the bottom end of the internal resistor feedback chain for fixed output voltage parts, and
should be connected to ground.

OUTPUT
INPUT
This is the power output of the device and is electrically connected to the TAB.
This is the input supply pin for both the control circuitry and the pass device.
