KF12

The KF00 series are very low drop regulators available in SO-8 package and in a wide range of output voltages.The KF12 belongs to KF00 series.

Features of the KF12 are:(1)very low dropout voltage (0.4v);(2)very low quiescent current (typ. 50 ma in off mode, 500ma in on mode);(3)output current up to 500mA;(4)logic-controlled electronic shutdown;(5)output voltagesof 1.25; 1.5; 2.5; 2.7;3; 3.3; 3.5; 4; 4.5; 4.7; 5;5.2; 5.5; 6; 8; 8.5;12v;(6)internal current and thermal limit;(7)only 2.2mf for stability;(8)available in ± 2% accuracy at 25;(9)supply voltagerejection: 70 db(typ.);(10)temperature range: -40 to 125.

The absolute maximum ratings of the KF12 can be summarized as:(1):the symbol is Vi,the parameter is DC input voltage,the value is -0.5 to 20,the unit is V;(2):the symbol is Io,the parameter is output current,the value is internally limited;(3):the symbol is Ptot,the parameter is power dissipation,the value is internally limited,the unit is ;(4):the symbol is Tstg,the parameter is storage temperature range,the value is -40 to 150,the unit is ;(5):the symbol is Top,the parameter is operating junction temperature range,the value is -40 to 125,the unit is .
