AOZ1010
EZBuck™ 2A Simple Regulator
General Description
The AOZ1010 is a high efficiency, simple to use, 2A buck
regulator. The AOZ1010 works from a 4.5V to 16V input
voltage range, and provides up to 2A of continuous
output current with an output voltage adjustable down to
0.8V.
The AOZ1010 comes in an SO-8 package and is rated
over a -40°C to +85°C ambient temperature range.
