APE8873
DESCRIPTION
The APE8873 is a low dropout linear
regulator which is designed to power a DC fan and delivers up to 500mA output current. The output voltage follows the 1.6 times of VSET voltage and typical dropout voltage is only 150mV (typical) at 500mA output current. The V SET voltage must be larger than 1V to guarantee V O 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 device against current over-loads and over temperature. The APE8873 is available in a SOP-8 package.
