RT9027B - (RT9027A / RT9027B) Linear Fan Driver

Download the RT9027B datasheet PDF. This datasheet also covers the RT9027A variant, as both devices belong to the same (rt9027a / rt9027b) linear fan driver family and are provided as variant models within a single manufacturer datasheet.

General Description

The RT9027A/B is a high performance positive voltage regulator designed for very low dropout voltage up to 0.5 Amps.

The VSET voltage must be larger than 1V to guarantee that VOUT is 1.6 times of VSET.

When VSET is less than 1V, the IC will be shutdown.

Key Features

  • z z z z z VOUT Follows 1.6 Times of VSET 150mV Dropout @ 0.5A Over Current and Over Temperature Protection FON Pin Turns VOUT Fully On RoHS Compliant and 100% Lead (Pb)-Free.

RT9027A/B Linear Fan Driver General Description The RT9027A/B is a high performance positive voltage regulator designed for very low dropout voltage up to 0.5 Amps. The VSET voltage must be larger than 1V to guarantee that VOUT is 1.6 times of VSET. When VSET is less than 1V, the IC will be shutdown. The FON pin turns VOUT to fullyon when FON is given low. For RT9027B (EN version), FON pin is equivalent to EN pin. The RT9027A/B provides excellent regulation over variations in line, load and temperature. The RT9027A/B is available in the SOP-8 package.
