LR18115
LINEAR INTEGRATED CIRCUIT
1.6X LINEAR FAN DRIVER
WITH V_OUT FULLY ON
CONTROL
 DESCRIPTION
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. V_OUT voltage follows the 1.6 times of
V_SET voltage until it reaches V_IN voltage. The V_SET voltage must be
larger than 1V to guarantee V_OUT 1.6 times of V_SET. When given low,
V_OUT can be fully turned on by FON pin. Good regulation over
variation in line, load and temperature is also provided by UTC
LR18115.
 FEATURES
