AX993-1.6X Linear Regulator for DC Fan Driver


AX993-1.6X Linear Regulator for DC Fan Driver Control DataSheet

GENERAL DESCRIPTION
    The AX993 is a low dropout linear regulator which is designed to power a DC fan and delivers up to 600mA output current. The output voltage follows the 1.6 times of VSET voltage and typical dropout voltage is only 150mV (typical) at 600mA output current. The VSET voltage must be larger than 1V to guarantee VO 1.6 times of VSET. An enable pin further reduces power dissipation while shut-down. The features of current limit (with fold back current) and over temperature protection protect the deviceagainst current over-loads and over temperature. The AX993 is  available in a SOP-8 package.

FEATURES
- Low Dropout Voltage: 150mV@0.6A
- VO Follows 1.6 times of VSET
- Enable/Shutdown function
- Stable with Low ESR Ceramic Capacitors
- Current-Limit and Thermal Shutdown Protection
- SOP-8 Pb-Free Package
