1.26V Adjustable High-Precision Shunt Regulators

The TA76432 series consists of adjustable high-precision shunt regulators whose output voltage (VKA) 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.

Features

• Precision reference voltage: VREF = 1.26 V ± 1.4 (Ta = 25°C)

• Small temperature coefficient: |αVREF| = 30 ppm/°C (typ.)

• Adjustable output voltage: VREF ≤ VOUT ≤ 19 V

• Minimum cathode current for regulation: Ikmin = 0.5 mA (max.)

• Operating temperature: Ta = −40 to 85°C

• The TA76432FT is housed in an ultra-thin UFV package. (thickness: 0.7 mm typ.)

• Packages: UFV (TA76432FT), SMV (TA76432FC), PW-Mini (TA76432F/FR) and LSTM (TA76432S)
