TA76433FC

The TA76433FC is suitable for the secondary side difference amplifier of the switching regulator of 1.8 V to 2 V class.It differs from the conventional shunt regulator (TA76431/432 series) of our company, the power supply input terminal which became separate of the cathode terminal is set up. Since the cathode terminal of the detection side and the input terminal of the power supply side is separate, a cathode terminal can operate from 0.2 V.  .Features of the TA76433FC are:(1)Separate power supply input pin (VCC) and cathode pin (K) ; (2)Precision reference voltage: VREF = 1.26 V ± 1.4% (Ta =25) ; (3)Maximum cathode voltage: 15 V ; (4)Maximum cathode current: 20 mA ; (5)Cathode voltage: 0.2 to 14 V ; (6)Cathode current: 0.4 to 20 mA ; (7)Operating temperature: Ta = -40 to 85 ; (8)Packages: SMV can be mounted on a 3.1 * 3.0 mm space.

The absolute maximum ratings of the TA76433FC can be summarized as:(1)Power supply voltage: 15 V ; (2)Cathode voltage : VCC V ; (3)Reference voltage : 7 V ; (4)Cathode current:20 mA ; (5)Cathode-anode reverse current : 10 mA ; (6)Reference current :50  A ; (7)Reference-anode reverse current :10 mA ; (8)Power supply current :3 mA ; (9)Power dissipation :0.2 W; 0.38 (Note)W ; (10)Thermal resistance :625/W   328 (Note)/W ; (11)Operating temperature:-40~85 ; (12)Junction temperature :150 oC ; (13)Storage temperature:-55~150 oC .

The electrical characteristics(Ta=25) of the TA76433FC can be summarized as:(1)Reference voltage :1.242V MIN. 1.26V TYP. 1.278VMAX.; (2)Deviation of reference input voltage overtemperature: 5mV TYP.,15mV MAX.; (3)Ratio of change in reference input voltage to the change in power supply voltage :-0.3mV/V TYP. -1.5 mV/V MAX.If you want to know more information such as the electrical characteristics ,please download the datasheet in www.seekdatasheet.com .
