XC6401FF45DR

The XC6401FF45DR is one member of the XC6401 series.This series is designed as one kind of highly accurate,dual,low noise,CMOS LDO voltage regulators. Performance features of the series includes low output noise,high ripple rejection ratio,low dropout and very fast turn-on times.The XC6401FF45DR includes a reference voltage source,error amplifiers, driver transistors,current limiters and phase compensators internally. The XC6401's current limiters' foldback circuit also operates as a short protect for the output current limiter.The output voltage for each regulator is set independently by laser trimming. Voltages are selectable in 50mV steps within a range of 0.8V to 5.0V.The XC6401 series is also fully compatible with low ESR ceramic capacitors, reducing cost and improving output stability.

The XC6401FF45DR can be used in mobile phones,cordless phones and radio communication equipment,portable games,cameras,video recorders and portable audio equipment,PDAs.The features can be summarized as:(1)maximum output current:more than 150mA (300mA limit);(2)dropout voltage:100mV @100mA;(3)operating voltage range:1.5V to 6.0V;(4)output voltage range:0.8V to 5.0V (50mV increments);(5)low power consumption:25A (TYP.);(6)standby current:less than 0.1A (TYP.);(7)high ripple rejection:70dB @1kHz;(8)operating temperature range:-40 to +85;(9)low ESR capacitor compatible:ceramic capacitor;(10)ultra small packages:SOT-26W,USP-6B,USP-6C.

The absolute maximum ratings of the XC6401FF45DR can be summarized as:(1)input voltage:6.5 V;(2)output current:700 mA;(3)output voltage:VSS-0.3 to VIN+0.3 V;(4)EN pin voltage:VSS-0.3 to 6.5 V;(5)operating temperature range:-40 to +85 ;(6)storage temperature range:-55 to +125 .If you want to know more information such as the electrical characteristics about the XC6401FF45DR,please download the datasheet in www.seekic.com .
