V_O Follows 1.6 times of V_SET
Enable/Shutdown function
Stable with Low ESR Ceramic Capacitors
Current-Limit and Thermal Shutdown Protection
SOP-8 Pb-Free Package
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
V_SET 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 V_SET. 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.
