1.6x Linear DC Fan Driver with VOUT Fully on Control AP2113

Preliminary Datasheet

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 70µA, 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
