TA76L431FB
TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA76L431FB
2.495 V Adjustable High-Precision Shunt Regulators
These devices are adjustable high-precision shunt regulators
whose output voltage (VKA) can be set arbitrarily using two
external resistors.
The devices have a precise internal reference voltage of 2.495 V,
enabling them to operate at low voltage. In addition, they can be
used as zener diodes to perform temperature compensation.

Usage Precautions
1. TA76L431FB
These products contain MOS elements. Please take care to avoid generating static electricity when handling
these devices.
2. TA76L431FB
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 absolute maximum rating
values specified in these datasheets so as to allow an operational safety margin.
Use of a laminated ceramic capacitor is recommended
