EZ1588

2.0A Low Dropout

Positive Voltage Regulators

POWER MANAGEMENT

Description

Features

The EZ1588 is a high performance positive voltage

regulator designed for use in applications requiring low

dropout performance at 2A. Additionally, the EZ1588

series provides excellent regulation over variations in line,

load and temperature.

u Low dropout performance: 1.3V max.

u Full current rating over line and temperature

u Fast transient response

u ±2% total output regulation over line, load

and temperature

u Adjust pin current max. 90µA over temperature

u Fixed/adjustable output voltage

u Line regulation typically 0.005%

u Load regulation typically 0.05%

u TO-220 or TO-263 packages

Outstanding features include low dropout performance

at rated current, fast transient response, internal

current limiting and thermal shutdown protection of the

output device.

The EZ1588 series are three terminal regulators with

fixed and adjustable voltage options available in popular

packages.

Applications

u Memory supplies

u Graphics core supplies

u 2.5V to 3.6V microprocessor supplies

u Low voltage logic supplies

u Battery-powered circuitry

u Post regulator for switching supply
