0.8 & 1.0 Amp Positive

Voltage Regulators

POWER MANAGEMENT

Description

The EZ1117 series of high performance positive voltage

regulators are designed for use in applications requiring

low dropout performance at up to 0.8A.

Additionally, the EZ1117 series provides excellent

regulation over variations in line, load and temperature.

Outstanding features include low dropout performance

at rated current, fast transient response, internal

current limiting and thermal shutdown protection of the

output device.

The EZ1117 series of three terminal regulators offer fixed

and adjustable voltage options available in the space

saving SOT-223 and TO-263 packages.

EZ1117

Features

Low dropout performance: 1.2V max.

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

Line regulation 0.2% max.

Load regulation 0.4% max.

SOT-223 and TO-263 packages

Applications

Low voltage microcontrollers
