1.26-V Adjustable High-Precision Shunt Regulators
The TA76432 series consists of adjustable high-precision shunt
regulators whose output voltage (V
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 3-V
switching-regulator systems. In addition, they can be used as
zener diodes to perform temperature compensation.
Features
Precision reference voltage: V
Small temperature coefficient: |αV
Adjustable output voltage: V
Minimum cathode current for regulation:
I
Operating temperature: Ta = −40~85°C
Packages: UFV (TA76432FT), SMV (TA76432FC),
The TA76432FT is housed in an ultra-thin UFV package.
(thickness: 0.7 mm typ.)
