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 packa...
