TA76432Fx

Manufacturer Part Number
TA76432Fx
Description
(TA76432xx) 1.26-V Adjustable High-Precision Shunt Regulators
Manufacturer
Toshiba Semiconductor
Datasheet
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.

... The oscillation frequency of these devices is determined by the value of the capacitor connected between the anode and the cathode. When establishing maximum operating condition parameters, please derate the maximum rating values specified in these datasheets allow an operational safety margin. 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 ...
