1A Low Dropout Linear Regulator

General Description

Features

The AOZ1117 is a low dropout positive adjustable or

fixed-mode regulator with minimum of 1A output current

capability. The product is specifically designed to provide

well-regulated supply for low voltage IC applications such

as high-speed bus termination and low current 3.3V logic

supply. The AOZ1117 is also well suited for other appli-

cations such as VGA cards. The AOZ1117 is guaranteed

to have lower than 1.4V dropout at full load current mak-

ing it ideal to provide well-regulated outputs of 1.25V to

5.0V with 2.75V to 14V input supply.

● 1.4V maximum dropout at full load current

● Fast transient response

● Output current limiting

● Built-in thermal shutdown

● Good noise rejection

● 3-terminal adjustable or fixed 1.5V, 1.8V, 2.5V, 3.3V,

or 5.0V

● TO252 package

Applications

● PC peripheral

● Communication
