EZ1585C & EZ1585I

4.6 Amp Positive

Voltage Regulator

POWER MANAGEMENT

Description

Features

The EZ1585 series of high performance positive voltage

regulators are designed for use in applications requiring

low dropout performance at up to 4.6A. Additionally, the

EZ1585 series provides excellent regulation over

variations in line, load and temperature.

Low dropout voltage: 1.3V max. for EZ1585C and

1.4V max. for EZ1585I

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 (EZ1585C)

Line regulation typically 0.015%

Load regulation typically 0.05%

Outstanding features include low dropout performance

at rated current, fast transient response, internal

current limiting and thermal shutdown protection of the

output device.

Industrial temperature range (EZ1585I)

TO-220 and TO-263 packages. Available in RoHS

compliant package

A variety of options are available for maximum flexibility:

the EZ1585C is intended for commercial applications and

has both fixed and adjustable voltage options; the

EZ1585I is intended for industrial applications and is

adjustable only.

Applications

Printer and plotter supplies

All devices are available in the popular TO-220 and Instrumentation

TO-263 packages.

Medical equipment

Microcontroller systems

Telecommunication systems

Motherboards
