TA8214K

TOSHIBA Bipolar linear Integrated Circuit Silicon Monolithic TA8214K Multi Output Voltage Regulator (8.3V output) The TA8214K is voltage regulator IC, designed for car audio use, has built−in 4 outputs. (fixed 1 output and changed 3 outputs.) The input−output differential voltage : VDIF is very small. (VDIF = 0.3V (typ.)) Because each outputs consist of PNP transistor. In addition, protection of over voltage, output short and thermal shut down are involved. Features · 4 channel outputs OUT1 : 8.3V (typ.) / 100mA (max.) .... fixed output OUT2 : 8.3V (typ.) / 100mA (max.) OUT3 : 8.3V (typ.) / 300mA (max.) switchable output OUT4 : 8.3V (typ.) / 100mA (max.) · Very small input−output differential voltage VDIF = 0.3V (typ.) · Built−in various protection circuits Over voltage, Output short, Thermal shut down · Input operating voltage VIN (opr) = 9.3~18V Weight: 2.19g (typ.)

(2) Power limiting register : RSD If VIN is too high, insert a power limiting register : RSD to reduce power dissipation of IC. (3) Input surge protective zener diode : ZD Though an over voltage protective circuit (for positive surge) is built in, if excessive surge is inp...
