ZTL431, ZTL432

Cost effective adjustable precision shunt regulator

Description

The ZTL431 and ZTL432 are three terminal The ZTL432 has the same electrical specifications

adjustable shunt regulators offering excellent as the ZTL431 but has a different pin out in

temperature stability and output current SOT23 (F-suffix) and SOT23F (FF-suffix).

handling capability up to 100mA. The output

Both variants are available in 2 grades with

initial tolerances of 1% and 0.5% for the A and

B grades respectively.

voltage may be set to any chosen voltage

between 2.5 and 20 volts by selection of two

external divider resistors.

These are functionally equivalent to the TL431/

TL432 except for maximum operation voltage,

and have an ambient temperature range of -40

to 125°C as standard.

The devices can be used as a replacement for

zener diodes in many applications requiring an

improvement in zener performance.
