ZTL431, ZTL432

Cost effective adjustable precision shunt regulator

Description

The ZTL431 and ZTL432 are three terminal

adjustable shunt regulators offering excellent

temperature stability and output current

handling capability up to 100mA. The output

voltage may be set to any chosen voltage

between 2.5 and 20 volts by selection of two

external divider resistors.

The devices can be used as a replacement for

zener diodes in many applications requiring an

improvement in zener performance.

The ZTL432 has the same electrical specifications

as the ZTL431 but has a different pin out in

SOT23 (F-suffix) and SOT23F (FF-suffix).

Both variants are available in 2 grades with

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

B grades respectively.

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.
