1.26-V Adjustable High-Precision Shunt Regulators
These devices are adjustable high-precision shunt regulators
whose output voltage (V
external resistors.
These devices have a precise internal reference voltage of 1.26 V,
enabling them to operate at low voltage.
These devices are ideal for use as error amplifiers in 3-V
switching-regulator systems. In addition, they can be used as
zener diodes to perform temperature compensation.

... Use of a laminated ceramic capacitor is recommended. (3) Precautions when handling anode pin of TA76432FT/TA76432FC Pin 2 and pin 5 should normally be shorted together. If only pin 5 is used, pin 2 should either be left open or always kept at a lower potential than pin 5. Do not leave pin 5 open and use pin 2 only. ...
