SOT23-3L

Description

The TLVH431 is a low power programmable

shunt voltage reference, with guaranteed

temperature stability over the entire operating

temperature range.

SOT323-6L

Features

• Adjustable output voltage: 1.24 V to 18 V

• Low operating current: 100 µA at 25 °C

• 0.25%, 0.5%, 1% and 1.5% voltage precision

• Sink current capability up to 60 mA

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.

• -40 to +125 °C temperature range

• 100 ppm/°C maximum temperature coefficient

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.

• Available in SOT23-3L, SOT23-5L and

SOT323-6L packages

Applications

The low operating current is a key advantage for

power restricted designs.
