General Description
The AP2113 is a low dropout high performance linear
regulator which is specially designed to drive a DC
fan, the regulator delivers output current 600mA in
minimum.
The AP2113 provides low quiescent current
consumption 70
µA, over current limit protection and
load short current protection with fold-back limitation
50mA, which are ideal for battery powered system
application.
The AP2113 output voltage (V
OUT
) follows 1.6 times
of V
SET
input voltage until it reaches V
IN
voltage
m inus dropout voltage (V
DROP
) at adjustable mode
(set FON

pin logic high). The V
SET
voltage must be
larger than 1.0V to guarantee V
OUT
1.6 times of V
SET
.
An FON
________
pin turns V
OUT
fully on when set logic low.
The AP2113 is available in standard SOIC-8 and
SOT-23-5 packages.
