TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA76433FC
TA76433FC
High-Precision Shunt Regulators with Adjustable Output Voltage
Due to the increasing requirement for low power dissipation
levels, 3-V power supply systems in electronic equipment are now
in greater demand than conventional 5-V power supply systems.
Toshiba has developed the TA76433FC, a high-precision shunt
regulator with adjustable output voltage is aimed for use in even
lower voltage applications.
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.
It is suitable for the secondary side difference amplifier of the
switching regulator of 1.8 V to 2 V class.
Features
· Separate power supply input pin (VCC) and cathode pin (K)
· Precision reference voltage: VREF = 1.26 V ± 1.4% (Ta = 25ºC)
· Maximum cathode voltage: 15 V
· Maximum cathode current: 20 mA
· Cathode voltage: 0.2 to 14 V
· Cathode current: 0.4 to 20 mA
· Operating temperature: Ta = −40 to 85ºC
· Packages: SMV can be mounted on a 3.1 × 3.0 mm space.
Weight: 0.014 g (typ.)
