ZXRE250/ZXRE252

VERY LOW CATHODE CURRENT ADJUSTABLE

PRECISION SHUNT REGULATOR

Description

Pin Assignments

The ZXRE250 and ZXRE252 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

36 volts by selection of two external divider resistors.

REF

ANODE

ZXRE250 has the same electrical specifications as the

industry standard ‘431 except that it features a very low

minimum cathode current for regulation. The typical value of

40µA makes the parts ideal for very low power applications.

CATHODE

SOT23

The devices can be used as a replacement for zener diodes

in many applications requiring an improvement in zener

performance. The ZXRE250/2 is available in 2 grades with

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

respectively.
