The RS1117 is a 1A low-dropout positive voltage regulator. It is available in fixed and adjustable output voltage
versions. Over current and thermal protection are integrated onto the chip. Output current will limit as while it
reaches the pre-set current or temperature limit. The dropout voltage is specified at 1.4V Maximum at full rated
output current. The RS1117 series provides excellent regulation over line, load and temperature variations.
