TS431

Low voltage adjustable shunt reference

Features

■ Low voltage operation: 1.24 to 6V

■ 2%, 1% and 0.5% voltage precision

■ Wide operating range cathode current: 60µA to

30mA

■ Low output impedance: 0.2

Ω

■ Typically stable for any capacitive loads

■ ESD protection:

– Human body model: 2kV

– Machine model: 200V

■ 100ppm/°C temperature coefficient

Description

The TS431 is a low-voltage, three-terminal,

programmable shunt voltage reference.

The output voltage can be set to any value

between Vref (1.24V) and 6V with two external

resistors.

The TS431 is able to operate at a lower voltage

(1.24V) and lower cathode current than the widely

used TL431 and TL1431 shunt voltage reference.

When driving an optocoupler, the TS431 is

particularly useful for regulating 3.3V switching

power supplies.
