LR18115 1.6X LINEAR FAN DRIVER

The UTC LR18115 is a low output resistance 1.6X positive voltage linear fan driver with very low dropout voltage at up to 500mA. The UTC LR18115 consists of an error amplifier, output stage, voltage divider, over temperature protection, current limiting scheme and Fully Control logic. VOUT voltage follows the 1.6 times of VSET voltage until it reaches VIN v.
