DESCRIPTION

The EZ1086 series of high performance positive
voltage regulators are designed for use in applications
requiring low dropout performance at full rated c urrent.
Additionally, the EZ1086 series provides excellent
regulation over variations in line, load and temperature.

Outstanding features include low dropout perfor mance
at rated current, fast transient response, internal
current limiting and therm al shutdown protec tion 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 comm ercial
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.

PIN CONFIGURATIONS

PIN DESCRIPTIONS

Pin Pin Name Pin Function

1 ADJUST /

GROUND

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.

This pin is the bottom end of the internal resistor feedback chain for fixed output voltage parts,

and should be connected to ground.
2 OUTPUT This is the power output of the device, and is electrically connected to the TAB.
3 INPUT This is the input supply pin for both the control circuitry and the pass device.
