TA2015FN

The TA2015FN is a ripple filter IC,which is developed for low voltage operation(1.5V).It is especially suitable for supplying voltage for headphone stereo etc.

Features of the TA2015FN are:(1)built-in a power switch;(2)excellent ripple rejection ratio:RR=43dB(Typ.);(3)ripple filter output voltage can be controlled by external resistor;(4)output voltage is limited to VRF=1.5V (Typ.);(5)built-in two constant current sources;(6)excellent low voltage operation;(7)low quiescent supply current (Vcc=1.2V,Ta=25) ICC=0.7mA(Typ.);(8)operating supply voltage range.(Ta=25) VCC9opr) = 0.9 to 2.2V.

The maximum ratings of the TA2015FN can be summarized as:(1):the characteristic is supply voltage,the symbol is VCC,the rating is 4.5,the unit is V;(2):the characteristic is constant current source output voltage,the symbol is VS,the rating is 4.5,the unit is V;(3):the characteristic is constant current source output current,the symbol is IS,the rating is 10,the unit is mA;(4):the characteristic is ripple filter output current (built-in transistor),the symbol is IRF,the rating is 20,the unit is mA;(5):the characteristic is power dissipation,the symbol is PD,the rating is 300,the unit is mW;(6):the characteristic is operating temperature range,the symbol is Topr,the rating is -25 to 75,the unit is ;(7):the characteristic is storage temperature range,the symbol is Tstg,the rating is -55 to 150,the unit is .
