Diodes AP2113 User Manual

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 of V m (set FON larger than 1.0V to guarantee V An FON

The AP2113 is available in standard SOIC-8 and SOT-23-5 packages.
