APE8873

Advanced Power Electronics Corp. FEATURES Low Dropout Voltage: 150mV@0.5A 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 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. 1.6X LINEAR REGULATOR FOR DC FAN DRIVER CONTROL TYPICAL APPLICATION U1 VIN=5V 2 VSET C1 2.2uF 4 1 VIN VSET EN GND 5,6,7,8 C2 2.2uF FAN VO 3 Vo=1.6 X V SET APE8873 PACKAGE ORDERING INFORMATION APE8873X Package Type M : SOP-8L 8873M Y WW SSS Part number ID code: internal WW: 01~52 Year: 8 : 2008 Data and specifications subject to change without notice 1 200808283 Free Datasheet http://www.Datasheet4U.com Advanced Power Electronics Corp.
