Description

The TLVH431 is a low power programmable

shunt voltage reference, with guaranteed

temperature stability over the entire operating

temperature range.

The output voltage may be set to any value

between 1.24 V and 18 V by means of an external

resistor divider.

The TLVH431 operates with a wide current range

from 100 µA to 60 mA with a typical dynamic

impedance of 0.22

Ω.

Available in SOT23-3L, SOT23-5L and SOT323-

6L surface mounted packages, it can be designed

in applications where space saving is a critical

issue.

The low operating current is a key advantage for

power restricted designs.
