3 Amp Positive Voltage Regulator

POWER MANAGEMENT

Description

Features

The EZ1085 series of high performance positive voltage

regulators are designed for use in applications requiring

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

EZ1085 series provides excellent regulation over

variations in line, load and temperature.

Low dropout voltage: 1.3V max. for EZ1085C,

1.4V max. for EZ1085I

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 (EZ1085C)

Line regulation typically 0.015%

Load regulation typically 0.05%

Industrial temperature range (EZ1085I)

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 EZ1085C has both fixed and adjustable voltage

options and is designed for use in commercial applica-

tions and the EZ1085I is adjustable only for industrial

applications.

Applications

Printer and plotter supplies

Pin Descriptions

Pin Name Pin Function

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.
