The AX1117 Series are available in fixed and adjustable output voltage versions. Over current and thermal overload protection

are integrated onto the chip. Output current will decrease while it reaches the preset current or temperature limit. The dropout

voltage is specified at 1.2V Maximum at full rated output current. AX1117 Series provide excellent regulation over variations due

to changes in line, load and temperature. AX1117 Series are three terminal regulators and available in popular packages.
