1.26V Adjustable High-Precision Shunt Regulators

The TA76432 series consists of adjustable high-precision shunt

regulators whose output voltage (V

) can be set arbitrarily

using two external resistors.

These devices have a precise internal reference voltage of 1.26 V,

enabling them to operate at low voltage.

The devices are ideal for use as error amplifiers in 3V

switching-regulator systems. In addition, they can be used as

zener diodes to perform temperature compensation.

Usage Precautions

(1)

TA76432FT, TA76432FC, TA76432F/FR, TA76432S

These products contain MOS elements. Please take care to avoid generating static electricity when

handling these devices.

TA76432FT, TA76432FC, TA76432F/FR, TA76432S

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.

Precautions when handling anode pins 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.

Note 3: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the

significant change in temperature, etc.) may cause this product to decrease in the reliability significantly

even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute

maximum ratings and the operating ranges.

Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook

(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test

report and estimated failure rate, etc).
