LR18115
LR18115 is 1.6X LINEAR FAN DRIVER manufactured by Unisonic Technologies.
UNISONIC TECHNOLOGIES CO., LTD LINEAR INTEGRATED CIRCUIT 1.6X LINEAR FAN DRIVER WITH VOUT 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 500m A. 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 voltage. The VSET voltage must be larger than 1V to guarantee VOUT 1.6 times of VSET. When given low, VOUT can be fully turned on by FON pin. Good regulation over variation in line, load and temperature is also provided by UTC LR18115. - Features - VOUT Follows 1.6 Times of VSET - 0.3Ω Output Resistance @ 0.5A - Over Temperature Protection - Current Limiting Protection - FON Pin to Turn VOUT Fully On - ORDERING INFORMATION Ordering Number LR18115G-S08-R Package SOP-8 Packing Tape Reel - MARKING .unisonic..tw Copyright © 2015 Unisonic Technologies Co., Ltd 1 of 5 QW-R102-039.F - PIN CONFIGURATION FON 1 VIN 2 VOUT VSET 4 LINEAR INTEGRATED CIRCUIT 8 GND 7 GND 6 GND 5 GND - PIN DESCRIPTION PIN NO. 1 2...
