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 (VOUT) follows 1.6 times of VSET input voltage until it reaches VIN voltage minus dropout voltage (VDROP) at adjustable mode (set FON

________

pin logic high). The VSET voltage must be larger than 1.0V to guarantee VOUT 1.6 times of VSET. An FON

________

pin turns VOUT fully on when set logic low. The AP2113 is available in standard SOIC-8 and SOT-23-5 packages.

Features • Output Voltage in Adjustable Mode Follows 1.6

Times of VSET (VOUT/VSET=1.6±3%) • Low Quiescent Current: 70µA (Typ) • Guarantee 0.6A Continuous Load • Switchable Adjustable Mode/Full Speed Mode • Over Current Protection • Short Current Protection with Fold-back

Limitation: 50mA • Low Dropout Voltage:

150mV @ 600mA (Typ) at Full Speed Mode 200mV @ 600mA (Typ) at Adjustable Mode

• OTSD Protection • Stable with 1.0µF Flexible Caps: Ceramic,

Tantalum and Aluminum Electrolytic • Operation Temperature Range: -40°C to 85°C • ESD: MM 300V, HBM 6000V Applications • Notebook Computer Fan Driver • Motherboards • Peripheral Cards
