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.
